Walk into a farm-supply store and the chicken-feed aisle can become confusing surprisingly quickly. Starter, starter/grower, grower, developer, layer, all-flock, mash, crumble, pellets, scratch grains, oyster shell, and grit may all be sitting within a few feet of one another.
Fortunately, feeding a backyard flock does not have to be complicated. For most chicken keepers, the foundation is a commercially prepared complete feed appropriate for the birds’ age and purpose. The nutritional needs of a newly hatched chick are very different from those of a hen producing eggs every day, which is why poultry feeds are formulated for different life stages.
The biggest mistake is often not choosing the wrong brand. It is diluting a nutritionally balanced feed with too many treats, grains, and extras—or giving young birds calcium-rich layer feed before their bodies need it.
Here is how starter, grower, layer, all-flock, treats, grit, and calcium fit together.
🐥 Chick Starter: The First Feed
Newly hatched chicks need a diet designed specifically for rapid growth.
Chick starter contains relatively high levels of protein along with the energy, vitamins, minerals, and other nutrients young birds require. Depending on the formulation, commercial chick starters commonly contain somewhere around 18 to 24% protein.
Many Extension feeding programs recommend starter feed for roughly the first six to eight weeks, although exact recommendations differ among feeds and production systems. Follow the instructions printed on your particular feed rather than switching simply because the calendar has reached a certain date.
For small chicks, starter is normally sold as a fine mash or crumble. Crumbles are easier for tiny birds to eat than full-size pellets.
Keep starter available so chicks can eat throughout the day rather than giving them one or two large meals.
Clean drinking water is equally important. Chicks should have continuous access to fresh water from the time they arrive in the brooder. As they grow, both feeder and waterer capacity must grow with them.
🌱 What Is Starter/Grower Feed?
Some manufacturers combine the first two stages into a single starter/grower formulation.
That can simplify feeding considerably. Instead of changing feeds at six or eight weeks, you follow the age range printed on the package and use the same complete ration through a larger portion of the bird’s development.
Do not assume all starter/grower feeds are identical, however. Protein levels, medication status, recommended ages, and intended species can differ.
The feed label matters more than the name on the front of the bag.
🐔 Grower Feed for Developing Pullets
After the early chick stage, future laying hens generally move to a grower or developer ration.
This stage supports continued growth without providing the high calcium concentration found in layer feed.
Depending on the feeding program, grower or developer feed may be used from approximately six to eight weeks until around 18 to 20 weeks, or until the pullets approach egg production.
University of Minnesota Extension, for example, recommends starter for the first six to eight weeks, followed by a grower or developer feed until the pullets begin laying at roughly 20 weeks.
A young chicken may already look nearly adult long before she lays her first egg. That does not mean she should automatically receive layer feed.
Her nutritional needs are still those of a growing bird.
🥚 When Should Chickens Start Eating Layer Feed?
Layer feed is formulated for hens that are entering or already in egg production.
A common transition point is around 18 to 20 weeks of age, depending on the breed, individual development, season, and instructions supplied with the feed. Beginning when pullets approach laying or when the first eggs appear is generally more useful than treating one exact birthday as universal.
Layer rations commonly contain around 16% protein, although formulations vary.
The major nutritional difference is calcium.
A laying hen uses considerable calcium to produce eggshells. Layer feed therefore contains much more calcium than starter or grower feeds—often approximately 3 to 4%, depending on the formulation.
That extra calcium is useful for an actively laying hen.
It is not appropriate for a young chick.
⚠️ Don’t Give Layer Feed to Young Chicks
One of the most important chicken-feeding rules is to avoid feeding high-calcium layer ration to growing birds.
Chicks and immature pullets need much less calcium than laying hens. Giving them a diet formulated for eggshell production can disrupt the balance of minerals their growing bodies require and can contribute to kidney damage and other health problems.
Penn State, Mississippi State, and University of Florida Extension guidance all caution against feeding layer diets to young birds.
Wait until the appropriate laying stage and follow the feeding instructions for the ration you are using.
This is especially important in a flock containing several ages of chickens. The convenient solution of filling one feeder with layer pellets may not be nutritionally appropriate when young birds are sharing it.
🐓 What Should Roosters Eat?
Roosters do not produce eggs, so they do not need the elevated calcium contained in layer feed.
In a flock consisting entirely of actively laying hens, a layer ration is straightforward.
A flock containing hens and roosters requires a little more thought.
University of Florida Extension suggests that an all-flock feed can be useful when males are present because it avoids giving roosters the extra calcium intended for laying hens. The hens can then receive an appropriate calcium source separately.
A general-purpose or all-flock ration can also simplify some mixed-age situations, provided the feed is appropriate for every bird that has access to it.
Always check the label because “all-flock” does not guarantee that every formulation is suitable for every age or poultry species.
🐣 Medicated vs. Non-Medicated Chick Starter
Some chick starters are sold as medicated feed, most commonly to help manage coccidiosis, a disease caused by microscopic parasites that can damage the intestinal tract.
The word “medicated” does not tell you everything you need to know. Read the label to determine what the feed actually contains and why it is included.
One particularly important question is whether your chicks were vaccinated against coccidiosis at the hatchery.
Some medicated feeds can interfere with the development of immunity from a live coccidiosis vaccine. University of Florida Extension therefore recommends finding out whether chicks received a coccidiosis vaccination before choosing medicated starter.
Recommendations can vary according to the medication, vaccination program, flock conditions, and current veterinary guidance.
If you are uncertain, ask the hatchery what vaccines the chicks received and follow the feed label or advice from a poultry veterinarian or knowledgeable Extension professional rather than guessing.
🍗 Meat Chickens Have Different Needs
Chickens being raised primarily for meat should not automatically follow the same feeding program as pullets being raised for eggs.
Fast-growing broiler strains have been selected for rapid growth and have different nutrient requirements. Commercial meat-bird programs commonly use a broiler starter followed by grower or finisher feeds.
If you are raising meat birds, choose a complete ration specifically designed for them and follow the feeding program recommended for that particular feed and type of bird.
Trying to make one feeding schedule fit egg layers, broilers, and breeding birds can create unnecessary nutritional problems.
This is another reason purpose and life stage matter more than simply choosing feed according to breed name.
🌾 Mash, Crumbles or Pellets?
Commercial chicken feed commonly comes in three physical forms: mash, crumble, and pellets.
Mash is finely ground and loose. Crumbles are essentially pellets that have been broken into smaller pieces, making them especially convenient for chicks and younger birds. Pellets are compressed pieces that are usually easier for mature chickens to pick up and can reduce some forms of feed waste.
University of Florida Extension notes that the physical form does not inherently change the nutritional value of an otherwise equivalent ration.
The best form therefore depends largely on bird size, availability, and what works well with your feeders.
Tiny chicks should not be expected to manage large pellets, but adult hens can usually eat pellets or crumbles without difficulty.
If your birds scatter enormous quantities of mash onto the floor, changing the feeder or trying pellets may reduce waste.
🥣 What Does “Complete Feed” Mean?
This is one of the most useful phrases to understand on a feed bag.
A complete poultry feed is formulated to supply the energy, protein, amino acids, vitamins, minerals, and other nutrients birds need when that ration makes up their primary diet.
That balance is important.
If a chicken fills up on corn, scratch grain, bread, vegetables, and table scraps, it eats less of the nutritionally complete feed. The problem is not necessarily that a single piece of corn or lettuce is harmful. The problem is that large quantities of nutritionally incomplete foods displace the balanced ration.
Mississippi State Extension specifically warns that adding significant quantities of grains or supplements to complete poultry feed can upset the nutritional balance it was formulated to provide.
Think of the complete ration as the meal and extras as extras.
🌽 Is Scratch Grain Chicken Feed?
Scratch is enormously popular with chickens.
That does not make it a complete diet.
Scratch grain is usually a mixture of grains such as corn, wheat, oats, or other seeds. Toss a little onto the ground and a flock will enthusiastically scratch and search for every piece.
That makes scratch useful as an occasional treat and enrichment activity.
It should not replace balanced poultry feed.
A hen that eats a large amount of scratch may consume fewer pellets or crumbles and therefore receive less protein, calcium, vitamins, and other nutrients than she needs.
Treat scratch like chicken candy rather than chicken dinner.
🍓 What Treats Can Chickens Eat?
Chickens are enthusiastic omnivores and will investigate an enormous variety of foods.
Small amounts of appropriate fruits, vegetables, grains, and other chicken-safe foods can provide variety and enrichment. Pumpkins, squash, leafy vegetables, berries, cucumber, and similar foods are common examples.
But “healthy for humans” does not automatically mean “nutritionally complete for chickens.”
Even perfectly safe vegetables can dilute the overall diet if birds eat so many that they ignore their balanced feed.
Treats are therefore best offered modestly rather than by the bucketful.
When introducing an unfamiliar food, check that it is safe for poultry rather than relying on the flock’s willingness to eat it. Chickens are curious eaters, not trained nutritionists.
🪨 What Is Chicken Grit?
Grit and calcium are frequently confused, but they serve completely different purposes.
Chickens do not have teeth. Instead, hard food is physically ground in the muscular gizzard.
Insoluble grit—usually appropriately sized hard stone such as granite—can remain in the gizzard and help grind coarse foods.
Chickens eating only finely processed commercial feed may have little need for supplemental grit because that feed is already easily broken down. Chickens receiving whole grains, forage, treats, or other coarse foods may need access to appropriately sized insoluble grit.
Free-ranging chickens may pick up suitable small stones naturally, but providing commercial poultry grit removes some of the uncertainty.
Use the correct size for the age of the birds. Chick grit is smaller than grit intended for mature chickens.
🦪 Is Oyster Shell the Same as Grit?
No.
This distinction is important enough to remember:
Grit helps grind food. Oyster shell supplies calcium.
Crushed oyster shell dissolves and supplies calcium that laying hens can use for eggshell production. Insoluble granite grit is retained in the gizzard to help mechanically break down food.
One cannot reliably substitute for the other.
If supplemental calcium is needed, it is generally best offered free choice in a separate container rather than indiscriminately mixed into everybody’s feed. That allows laying hens to consume additional calcium without forcing young birds or roosters to eat the same amount.
A properly formulated layer feed already supplies significant calcium, so supplemental oyster shell is just that—a supplement rather than a replacement for layer ration.
🥚 What If Eggshells Are Thin?
Occasionally finding an unusual egg does not necessarily mean the flock has a calcium deficiency.
Eggshell quality can be affected by nutrition, age, heat, health, stress, and other factors.
If thin or soft shells become frequent, begin with the basics. Make sure hens are actually eating an appropriate complete layer ration and have constant access to clean water.
Providing free-choice oyster shell can give laying hens access to additional calcium when needed.
Do not simply start adding increasingly large amounts of calcium to the main feed. Persistent shell problems deserve a broader look at the birds’ diet and health.
🥚 Can You Feed Eggshells Back to Chickens?
Some keepers use properly prepared eggshells as an additional calcium source.
If you do, shells should be completely dried and crushed into very small pieces so they no longer resemble recognizable eggshells.
However, commercial crushed oyster shell is inexpensive, convenient, and specifically prepared for poultry, making it an easier option for many backyard keepers.
Whichever calcium source you use, remember that it does not replace a complete laying ration.
🌿 Do Free-Range Chickens Still Need Feed?
Yes.
Chickens with access to pasture may find insects, seeds, vegetation, and other edible material, but forage varies dramatically according to season, climate, stocking density, land quality, and weather.
A green yard is not a nutritionally formulated chicken ration.
Keep a complete feed available even when chickens spend much of the day foraging.
Anything they find outdoors can complement that diet rather than being expected to replace it.
The same principle applies on a larger homestead. Self-sufficiency does not mean asking animals to meet nutritional needs from whatever happens to grow nearby. Good livestock management starts with understanding what each species actually requires, something we also discuss in 10 Essential Skills for Successful Homesteading Self-Sufficiency.
📏 How Much Feed Does a Chicken Eat?
Feed intake varies with the bird’s size, genetics, age, production level, weather, and the energy content of the ration.
As a rough reference, Mississippi State Extension reports that an average laying hen may consume about 1/4 to 1/3 pound of feed per day.
That works out to roughly 4 to a little over 5 ounces, but it should not be treated as a strict daily ration for every hen.
Most backyard laying flocks are better managed with appropriate complete feed available freely throughout the day.
Watching consumption is still useful. A sudden decline in feed intake can be an early indication that something has changed with the flock or its environment.
Hot weather, illness, loss of water, stress, spoiled feed, and other problems can all alter eating behavior.
🍽️ Make Sure Every Chicken Can Reach the Feeder
Having enough feed in the coop is not the same as ensuring every chicken gets enough to eat.
Chickens establish a social hierarchy, and dominant birds can sometimes control preferred feeding areas.
Provide sufficient feeder space and watch the flock when it eats. Timid birds should be able to approach without continually being driven away.
Adding another feeding location can help in larger or more competitive flocks.
Feeder height matters too. For older birds, keeping the lip near back height can reduce scratching and wasted feed while still allowing comfortable access.
Avoid filling trough feeders to the brim. Chickens are remarkably talented at throwing food onto the floor.
💧 Feed and Water Work Together
No feeding program works without adequate water.
Chickens need fresh water for digestion, temperature regulation, metabolism, and egg production. A flock without drinking water may also stop eating.
Check water whenever you check feed.
Hot weather deserves particularly close attention because poultry can dramatically increase water consumption as temperatures climb.
Our guide to how to water chickens covers normal drinking needs, waterer cleaning, summer heat, freezing weather, and signs that your flock may need closer attention.
🌡️ Feeding Chickens During Hot Weather
Chickens commonly eat less when temperatures are very high.
That makes the quality of what they do eat particularly important.
A heat-stressed hen that fills up on scratch or treats may consume even less of the nutritionally balanced ration needed to support her body and egg production.
Keep complete feed available, provide plenty of cool fresh water, create shade and ventilation, and avoid relying on large quantities of treats as a strategy for managing heat.
Small portions of high-moisture chicken-safe foods can be enjoyable enrichment, but water and balanced feed remain the essentials.
❄️ Do Chickens Need Different Feed in Winter?
Healthy chickens still need a balanced complete ration during winter.
Cold weather may increase energy requirements and feed consumption, particularly when birds are using more energy to maintain body temperature. University of Minnesota Extension notes that feed intake can rise during cold weather.
That does not mean the flock needs to be switched automatically to a completely different homemade winter diet.
Keep their normal age-appropriate balanced ration available and monitor how quickly it is being consumed.
Scratch grains can be offered sparingly as an enrichment treat, but they should not displace the complete feed.
The most important winter nutrition strategy is often the least exciting one: make sure the feeder does not run empty and the water does not freeze.
🐓 Feeding a Mixed Flock
A flock containing laying hens, roosters, and birds that are not actively laying presents a special challenge because their calcium requirements differ.
One practical solution is an appropriate all-flock or general-purpose ration, with crushed oyster shell offered separately so laying hens can consume additional calcium.
Oregon State and University of Florida Extension both describe this approach for mixed flocks.
The key is still to read the particular feed label. Make sure it is formulated for the ages and types of birds actually sharing the feeder.
Very young chicks may still need a dedicated chick starter rather than whatever the adult flock is eating.
Mixed flocks are exactly where reading labels becomes more useful than memorizing a single feeding rule.
🏷️ How to Read a Chicken Feed Label
The front of a feed bag is mostly marketing. The label contains the information you actually need.
Check the species and life stage the feed is designed for. Look at the guaranteed analysis, including protein and calcium. Determine whether the feed is medicated, and read any warnings or withdrawal instructions associated with medications.
Look for feeding directions and recommended ages as well.
Two bags labeled “layer feed” may not have exactly the same formulation. Similarly, one manufacturer’s starter/grower ration may have feeding instructions that differ from another’s.
Use Extension recommendations to understand the principles, then use the label to manage the specific product in your feed bin.
🪣 Store Chicken Feed Properly
A high-quality ration loses its value if it becomes wet, moldy, stale, or contaminated by rodents.
Keep feed in a cool, dry location protected from moisture and pests. A tightly closing metal container works well in many chicken-keeping setups because it discourages rodents and prevents accidental access by other animals.
Do not continually pour new feed on top of old feed until forgotten material remains at the bottom for months.
Rotate your supply and clean storage containers periodically.
If feed smells musty, appears moldy, has become wet, or looks noticeably different from normal, do not feed it to the flock.
Buying enormous quantities may seem economical, but only if the feed remains fresh enough to use.
🥣 Should You Make Homemade Chicken Feed?
Mixing your own feed sounds like a natural extension of homesteading, but producing a genuinely complete poultry ration is more complicated than combining corn, oats, seeds, and a protein source.
Chickens require specific balances of amino acids, energy, vitamins, minerals, calcium, phosphorus, and other nutrients at different stages of life.
A mixture can look wholesome and varied while still being nutritionally deficient.
University of Minnesota Extension recommends complete commercial feed as a good option for small-flock owners. Farms with appropriate feed-mixing equipment and nutritional knowledge may formulate diets using grains and commercial concentrates, but that is different from improvising a mixture from pantry ingredients.
For most backyard flocks, a reputable complete feed is the simpler and safer foundation.
There are plenty of other ways to practice self-sufficiency without experimenting with an animal’s basic nutrition.
🐛 Do Chickens Need Extra Protein?
A complete feed appropriate for the bird’s age already contains protein formulated for that stage of production.
That means healthy chickens generally do not need routine handfuls of high-protein supplements added to an already balanced diet.
There are circumstances—such as certain management situations or veterinary concerns—where the diet may need adjustment, but adding more protein simply because “protein is good” does not automatically improve a ration.
If you believe the flock’s nutritional requirements have changed, choosing an appropriately formulated feed is usually more reliable than attempting to rebalance the existing ration with treats.
🪶 What About Feeding During the Molt?
Molting requires chickens to grow a substantial amount of new feather material, and flock management during this period often raises questions about protein.
A good-quality complete feed remains the foundation.
Depending on your flock and normal ration, some keepers choose a complete feed formulated with somewhat higher protein during the molt rather than loading birds with mealworms or other treats.
The important word is complete. Changing to another nutritionally balanced ration maintains the vitamin and mineral balance while adjusting the overall formulation.
Molt is a normal biological process, not a reason to replace dinner with snacks.
🚫 Common Chicken-Feeding Mistakes
Most feeding problems come back to a handful of simple issues.
Giving layer feed to chicks is one of the most important to avoid because of its elevated calcium. Feeding enormous amounts of scratch and table scraps can dilute a complete ration. Forgetting that roosters do not have the calcium requirements of laying hens can complicate mixed-flock feeding.
Using oyster shell as though it were grit—or grit as though it supplied calcium—confuses two completely different jobs.
Storing feed in damp conditions creates another avoidable risk.
And perhaps the simplest mistake is allowing the feeder to run empty while assuming chickens can make up the difference by foraging.
A balanced diet does not need to be elaborate. It needs to be consistent.
🐔 A Simple Feeding Plan for Most Backyard Layers
If all the terminology still seems complicated, the basic progression is straightforward.
Young chicks begin with a complete chick starter or appropriate starter/grower feed. Growing pullets transition to grower or developer feed according to the product instructions. Once hens approach or begin egg production, they move to a complete layer ration with the higher calcium required for eggshell formation.
Adult mixed flocks containing roosters or non-layers may be better suited to an all-flock ration, with calcium available separately for the laying hens.
Grit helps chickens grind coarse foods. Oyster shell provides calcium. Scratch and other treats are extras rather than the foundation of the diet.
And clean water should be available at all times.
Once those distinctions are clear, the wall of feed bags at the farm store becomes much less intimidating.
🌾 Good Nutrition Doesn’t Need to Be Complicated
Chickens will happily eat an astonishing variety of things, which can make feeding them seem more complicated than it really is.
Their enthusiasm is not the same as nutritional wisdom.
The simplest approach is usually the strongest one: make an appropriate complete feed the center of the diet, match it to the bird’s life stage and purpose, keep treats modest, provide grit when the diet requires it, and make additional calcium available to laying hens when appropriate.
Watch your flock as well as the feed bag.
Healthy birds should be active and alert, with normal eating and drinking patterns and body condition appropriate for their age and type. Sudden changes in appetite, weight, egg production, feathers, droppings, or behavior deserve attention rather than an automatic handful of supplements.
When the basics are right, feeding chickens becomes one of the easiest parts of the daily routine—and leaves more time for the considerably more entertaining business of watching the flock be chickens.
