Chicken Feeding Guide for Proper Nutrition

Feed is the biggest daily cost of keeping hens, and it also decides how healthy they look, how well they lay, and how long they live. Many new keepers toss in some grain and kitchen scraps and hope for the best. That works for a few weeks, then the problems start: thin eggshells, dull feathers, and birds that stop laying.
This chicken feeding guide explains what your flock needs at every stage of life, in plain language. You will find protein targets, daily amounts, safe treats, and the mistakes that cost keepers the most money. If you are just starting out, it also helps to read about the pluses and minuses of keeping chickens before you buy your first birds.

Why Chicken Nutrition Matters More Than Most Keepers Think

A chicken is a small animal with a fast metabolism. A good laying hen can produce close to 300 eggs a year, and each egg pulls protein, calcium, and energy out of her body. If the feed does not replace those nutrients, she borrows them from her own bones and muscles.
Good feeding is the base of flock care, and it connects directly to chicken health. Most of the “mystery” problems keepers write about online, like soft shells, feather picking, and slow growth, trace back to a feed gap rather than a disease.

What Chickens Actually Need

Chickens need six things from their diet: protein, carbohydrates, fats, vitamins, minerals, and clean water. Protein builds feathers, muscle, and eggs. Carbohydrates and fats give energy for scratching, walking, and staying warm.
Calcium and phosphorus build bones and eggshells, while vitamins A, D, and E support the immune system, eyes, and skin. Chickens are omnivores, so in a free-range setting they also eat insects, worms, seeds, and greens. A confined flock cannot do this, so the feed bag has to do the work.

A Real Example From a Small Backyard Flock

Take a family with six hens in a small garden. They fed only scratch grains for a month because the birds loved it. The egg count dropped from five a day to two, and the shells turned thin and pale.
Switching to a 16 percent layer feed and keeping scratch as a small afternoon treat fixed the problem within three weeks. Scratch grain is like candy for chickens. It tastes great, but it is low in protein and calcium, so it should never be the main meal.

Types of Chicken Feed and When to Use Them

Walk into any feed store and you will see several bags that look similar. The difference sits in the protein and calcium levels, which are matched to the bird’s age and job. Using the wrong bag is one of the most common errors.

Crumbles, Pellets, or Mash

Feed comes in three forms. Mash is finely ground and closest to the natural form, but hens can pick out their favorite bits and leave the rest. Pellets are compressed and reduce waste, though some small chicks struggle with them.
Crumbles are broken pellets and work well for most backyard flocks. Pick one form and stay with it, because switching often can make birds pick at their food for a few days.

Organic, Fermented, and Homemade Options

Some keepers prefer organic feed or fermented grains. Fermenting soaks the feed in water for two to three days, which can improve digestion and reduce waste. Many people report that birds eat less by weight because the feed is easier to absorb.
Homemade mixes are possible, but getting the amino acid balance right is hard. If you want to try one, ask a poultry nutritionist or your local extension office. The same principle applies when people make homemade dog food: the recipe must be balanced, not just fresh.

Feeding Chickens at Every Life Stage

Chickens change fast. A bird that needs 22 percent protein as a chick needs a very different diet as an adult hen. Matching feed to age saves money and prevents growth problems.

Chicks: Hatch to 8 Weeks

Chicks need a starter feed with 20 to 22 percent protein. Give it freely, so food is always in front of them. Use a shallow feeder and keep water close, because a chick that cannot find water will stop eating.
Medicated starter contains a coccidiostat to help against coccidiosis. Skip it if your chicks were vaccinated, since the medication can cancel the vaccine. Keep treats away for the first two weeks, and offer a pinch of fine chick grit if you give anything beyond starter.

Growers: 8 to 18 Weeks

Teenage birds are growing bones and muscle, but they are not laying yet. A grower feed with 16 to 18 percent protein fits well here. Do not put them on layer feed too early.
The extra calcium in layer feed can damage the kidneys of young birds. Wait until the first egg appears, or until about 18 to 20 weeks, before you switch.

Laying Hens

A laying hen needs layer feed with about 16 percent protein and 3.5 to 4 percent calcium. Most hens eat roughly 110 to 120 grams, or a quarter pound, per day. Keep a separate dish of crushed oyster shell on the side so hens can take calcium when they need it.
Hens that do not need extra calcium will usually ignore the dish. Those that are laying heavily will visit it often. This self-serve method works better than mixing extra calcium into the feed.

Molting Hens

Once a year, usually in autumn, hens drop their old feathers and grow new ones. Feathers are about 85 percent protein, so the body demands more of it. Raise the protein to 18 to 20 percent for the molt period.
Many keepers add a handful of dried mealworms or switch to an all-flock feed for a few weeks. Laying usually pauses during a molt, and that is normal.

Meat Birds

Broilers grow extremely fast and need high protein early on. Feed them a broiler starter at 20 to 23 percent protein, then a finisher near the end. Always remove feed for a few hours before processing, as it makes the process cleaner.

How Much Should You Feed Your Chickens?

A simple rule is to give each adult hen about a quarter pound of feed per day. A flock of eight hens will eat around two pounds a day, or roughly 60 pounds a month. Chicks eat less per bird but grow quickly, so check the feeder often.
Free feeding means keeping a full feeder available at all times. Most backyard keepers prefer this because hens regulate themselves well on a complete feed. Scheduled feeding twice a day also works, but it needs more time and watching.

Signs You Are Feeding Too Much or Too Little

Watch your birds, not only the bag. A healthy hen has a firm, rounded breast bone and bright eyes. You can check this by lightly feeling the keel bone.

• Too thin: sharp keel bone, pale comb, slow laying
• Too fat: waddling walk, fat around the vent, fewer eggs
• Wasted feed: lots of grain on the ground, which also attracts rats
• Well fed: glossy feathers, steady eggs, active scratching

Cutting Down on Waste

Hang feeders at the height of the hen’s back, and keep them under cover from rain. Wet feed grows mold quickly, and mold can make birds sick. Rodents can eat a surprising amount of grain overnight, so store feed in a metal bin with a tight lid.
Clean feeders and drinkers regularly. The same logic applies to pets, and keeping dog bowls clean shows how fast bacteria build up around food dishes.

Treats, Kitchen Scraps, and Foods to Avoid

Treats are fun to give and great for bonding, but they should stay under 10 percent of the daily diet. Too many treats dilute the balanced feed and lower egg quality.

Safe and Healthy Treats

• Leafy greens like spinach, kale, and lettuce
• Pumpkin, squash, and cucumber
• Cooked eggs, scrambled and chopped
• Dried mealworms and black soldier fly larvae
• Berries, watermelon, and apple slices without seeds
• Cooked oats and plain cooked rice

Foods You Should Never Give

Some everyday foods are risky for chickens. Avoid avocado, chocolate, raw or dried beans, green potato skins, and anything moldy. Salty and sugary snacks like chips and sweets are also a bad idea.
Onions and citrus are best kept to very small amounts. Never offer spoiled food, since chickens do not “know better” and will eat it anyway. If you spray your garden, read about pesticides safe for use with chickens first, because treated plants can harm a flock.

Water, Grit, and Calcium: The Overlooked Basics

Water matters as much as feed. A hen drinks around 250 to 500 milliliters a day, and much more in hot weather. An egg is mostly water, so a hen without fresh water will quickly stop laying.
Grit sits in the gizzard and grinds food, just like teeth. Birds on a complete feed need little of it, but free-range hens pick up their own from the soil. If your flock only eats feed and treats, offer a small dish of insoluble grit.

Hot Weather and Cold Weather Tips

In summer, place several waterers in shade and refresh them twice a day. Feed more of the cooler parts of the day, like early morning and evening, since hens eat less when it is hot.
In winter, hens burn more energy to stay warm. A handful of cracked corn in the late afternoon gives them a slow-burning energy boost overnight. Check that water has not frozen, because that is the most common winter feeding problem.

Common Chicken Feeding Mistakes

Even careful keepers slip up. Here are the mistakes that show up the most:

• Feeding layer feed to chicks or growers too early
• Using scratch grain as the main meal
• Letting feed get wet or moldy
• Forgetting the oyster shell for laying hens
• Switching feed brands suddenly, which upsets digestion
• Letting feeders run empty for even a day

If you are building a new setup, plan the feeding area when you design the housing. Our guide on how to build a chicken coop like a real farmer would covers layout ideas that keep feed dry and away from pests.

A Simple Weekly Routine That Works

A routine takes the guesswork out of feeding. Check feeders and water every morning, and top up as needed. Once a week, scrub the drinkers and look at the feed for damp patches or bugs.
Once a month, weigh a few birds or feel their keel bones, and adjust the feed if needed. Ten minutes of attention a week catches problems early and keeps your flock steady.

Frequently Asked Questions

What is the best food for chickens?

A complete commercial feed that matches the bird’s age is best. Use starter for chicks, grower for teens and layer feed for hens.

How much should I feed one chicken per day?

An adult hen eats about 110 to 120 grams, roughly a quarter pound, of feed each day.

Can chickens eat kitchen scraps?

Yes, in small amounts. Stick to vegetables, fruits and cooked grains, and avoid avocado, chocolate and moldy food.

When can chickens start eating layer feed?

Switch at about 18 to 20 weeks, or when the first egg appears.

Do chickens need grit?

Yes, if they do not free range. Grit helps the gizzard grind food, and free-range birds usually find it themselves.

Conclusion

Good chicken feeding comes down to a few clear habits: match the feed to the bird’s age, keep treats small, give fresh water daily and always offer calcium to laying hens. Watch your flock closely, since healthy birds show it in their feathers, energy and eggs.
Start with a complete feed, adjust with the seasons and avoid common mistakes. With this chicken feeding guide, your hens will have the nutrition they need to stay strong and productive for years.
