Chicken Feed Guide: How Much to Feed Your Flock (2026)
Published: June 11, 2026 · 10 min read
Ask any chicken keeper what their biggest ongoing expense is, and you'll get the same answer every time: feed. It accounts for roughly 70% of the cost of keeping a backyard flock, and getting the quantities right is the difference between healthy, productive hens and birds that are underweight, overfed, or simply not laying. Whether you're starting with three hens in a suburban coop or managing 50 birds on pasture, knowing exactly how much to feed—and what kind—saves you real money.
In this guide, we'll walk through feed quantities by bird type, break down the different feed formulations, and give you five proven ways to lower your feed bill without cutting corners on nutrition. When you're ready to run the numbers for your own flock, use our Chicken Feed Calculator to get an exact daily and monthly estimate.
How Much Feed Per Chicken Per Day
Feed consumption varies by breed, age, and purpose. A fast-growing Cornish Cross broiler eats nearly double what a mature Leghorn layer does, while chicks barely touch a few tablespoons a day. The table below gives you reliable daily amounts for the most common categories of backyard chickens.
| Bird Type | Daily Feed (lbs) | Daily Feed (cups) | Monthly Feed (lbs) | Example Breeds |
|---|---|---|---|---|
| Laying hen (adult) | 0.25 | ~½ cup | 7.5 | Leghorn, Rhode Island Red, ISA Brown |
| Broiler (growing) | 0.35 | ~¾ cup | 10.5 | Cornish Cross, Red Ranger |
| Dual-purpose (adult) | 0.30 | ~⅔ cup | 9.0 | Orpington, Wyandotte, Australorp |
| Pullet (8–20 weeks) | 0.18 | ~⅓ cup | 5.4 | All breeds during grow-out phase |
| Chick (0–8 weeks) | 0.10 | ~3 tbsp | 3.0 | All breeds during starter phase |
These numbers assume your birds get most of their nutrition from formulated feed. If they spend significant time free-ranging, you can reduce commercial feed by 20–30% during the growing season when insects and forage are abundant. In winter, free-range consumption drops to near zero, and you'll be back to full feed rations.
Feed Types Explained: What to Feed at Each Stage
Walking into a feed store, you'll see bags labeled Starter, Grower, Layer, and sometimes All-Purpose or Flock Raiser. Each formulation is designed for a specific life stage, and feeding the wrong one can cause serious problems—feeding layer feed to chicks, for example, delivers dangerously high calcium levels that can damage developing kidneys.
Starter Feed (0–8 weeks)
Starter feed contains 18–22% protein and is finely ground or crumbled so small chicks can eat it easily. Most starter feeds are medicated with amprolium to prevent coccidiosis, a common intestinal disease that kills young chicks. If your chicks have been vaccinated against coccidiosis, you must use unmedicated starter—the medication will neutralize the vaccine. Feed starter free-choice; chicks self-regulate and won't overeat at this stage.
Grower Feed (8–18 weeks)
Grower feed drops protein to 15–18% and removes the medication. Birds at this stage are building bone and muscle but don't yet need the high calcium levels that support eggshell production. Some keepers skip grower and switch straight from starter to layer at 18 weeks; either approach works as long as you don't introduce layer feed before 18 weeks.
Layer Feed (18+ weeks, or at first egg)
Layer feed contains 16–18% protein and 3.5–4.5% calcium—the extra calcium is critical for strong eggshells. Without it, hens pull calcium from their own bones, leading to thin shells, broken eggs, and eventually serious health issues. You can supplement calcium by offering crushed oyster shell in a separate feeder, which lets each hen self-regulate her intake.
All-Purpose / Flock Raiser
All-purpose feeds typically run 18–20% protein and are designed to work for mixed flocks of different ages and species. They're convenient if you keep chickens, ducks, and turkeys together, but you'll need to offer oyster shell separately for your layers since all-purpose feed doesn't contain enough calcium for egg production.
How Much Does Chicken Feed Actually Cost?
Feed is a recurring expense, not a one-time purchase, so understanding your monthly and yearly costs matters. As of 2026, a 50 lb bag of quality layer feed runs $16–22 at most farm supply stores, with organic feed priced $28–40 per 50 lb bag.
Here's what that looks like for different flock sizes:
| Flock Size | Monthly Feed (lbs) | Monthly Cost | Yearly Cost |
|---|---|---|---|
| 3 layers | 22.5 | $8–11 | $96–132 |
| 6 layers | 45 | $16–22 | $192–264 |
| 12 layers | 90 | $32–44 | $384–528 |
| 25 layers | 187.5 | $67–92 | $804–1,104 |
Prices assume standard layer feed at $18/50 lb bag (midpoint). Your actual costs will vary by region—feed tends to be cheaper in the Midwest and more expensive on the coasts and in the Northeast.
5 Ways to Reduce Feed Costs Without Shortchanging Your Birds
1. Free-Range When You Can
Chickens are natural foragers. Given access to pasture, they'll eat insects, grass, seeds, and weeds—cutting your commercial feed consumption by 20–30% during warm months. A 6-hen flock that free-ranges daily from April through October can save 100–150 lbs of feed per year. The trade-off: free-ranging exposes birds to predators, so balance your savings against your local fox, hawk, and coyote situation.
2. Ferment Your Feed
Fermenting feed—soaking it in water for 24–72 hours until it bubbles slightly—increases nutrient availability and makes feed more digestible. Studies from the University of Kentucky and backyard trials consistently show that fermented feed reduces total consumption by 10–15% because birds absorb more from less. The process is simple: put a day's worth of feed in a bucket, cover with dechlorinated water by an inch, stir daily, and feed once it smells slightly sour and yeasty.
3. Feed Kitchen Scraps Strategically
Chickens can eat most fruit and vegetable scraps, cooked grains, and leftover bread. Good options include apple cores, carrot peels, lettuce trimmings, squash guts, and cooked rice or pasta. Avoid: raw potato peels (contain solanine), avocado pits and skins (persin), chocolate, onions in large quantities, and anything moldy or spoiled. As a general rule, scraps should make up no more than 10–15% of a chicken's daily intake—the bulk of their nutrition still needs to come from balanced feed.
Pro tip: Keep a "chicken bucket" on your kitchen counter. Toss in vegetable peels, stale bread crusts, and apple cores throughout the day. Dump it in the run each evening. It's a small habit that noticeably trims your feed bill.
4. Grow Fodder
Sprouting barley, wheat, or oats into fodder trays is an inexpensive way to produce fresh greens year-round. A 50 lb bag of barley ($18–25) can produce 300–350 lbs of fodder—roughly $0.07 per pound of fresh feed. You'll need shallow trays, water, and about 20 square feet of space for a system that feeds 6 hens. The sprouting cycle takes 7 days, so a staggered rotation of trays gives you a daily harvest.
5. Buy in Bulk
A 50 lb bag costs $16–22. A one-ton bulk delivery drops the per-bag cost to $13–17—a 20–25% savings. The catch: you need dry, rodent-proof storage for 40 bags. If you keep 15 or more layers, bulk buying pays for itself within the first year. For smaller flocks, splitting a bulk order with neighbors or a local chicken-keeping group makes it practical.
Seasonal Feeding: Adjusting for Summer and Winter
Summer: More Water, Slightly Less Feed
In hot weather (above 85°F), chickens naturally eat less—typically 10–15% below normal. This is fine as long as egg production stays steady. What you cannot skimp on is water. A laying hen drinks roughly 1 pint of water per day in mild weather and up to 2 pints when temperatures hit 90°F. Place waterers in the shade and refresh them twice daily. Adding electrolytes to the water once a week during heat waves helps prevent stress-related production drops.
Winter: More Calories for Warmth
When temperatures drop below freezing, chickens burn extra calories to maintain body heat. Expect feed consumption to increase by 15–25% during cold snaps. A popular winter strategy is to offer a small scratch grains ration (about 1 tablespoon per bird) just before roosting time. The slow digestion of corn and other grains generates body heat overnight when birds are huddled on the roost.
Putting It All Together
Getting your chicken feed right comes down to three things: feeding the correct formulation for your birds' age, giving them the right quantity, and finding ways to offset costs where it makes sense. Start with the numbers from the table above, adjust based on what you observe in your coop, and experiment with one or two cost-saving methods at a time.
