Chickens can eat most table scraps you’d find on a dinner plate or cutting board, including vegetables, fruits, cooked grains, and small amounts of meat and eggs. The key rule is the 90/10 guideline: at least 90% of a chicken’s daily diet should come from a complete commercial feed, with table scraps and treats making up no more than the remaining 10%. That ratio keeps your flock well-nourished while letting them enjoy variety.
Fruits and Vegetables
Produce scraps are the easiest and safest category to share with your flock. Chickens will happily eat berries, apples, grapes, cucumbers, zucchini, leafy greens, peas, carrots, broccoli, and squash. Melon rinds are a particular favorite. Toss watermelon, cantaloupe, or honeydew rinds into the run and your birds will peck them clean. Corn on the cob, cooked or raw, is another crowd-pleaser.
You can feed the parts you’d normally throw away: carrot tops, broccoli stems, the wilted outer leaves of lettuce, strawberry tops, and apple cores. Just remove apple seeds first, since they contain small amounts of cyanide compounds. A few seeds won’t cause immediate harm, but there’s no reason to make it a habit.
Cooked Grains, Bread, and Pasta
Leftover rice, pasta, oatmeal, and bread are all safe for chickens. Cooked grains are easier for them to digest than raw ones, though chickens can handle whole raw grains like corn, wheat, barley, and oats when you also provide insoluble grit (small stones they use to grind food in their gizzard). Stale bread, crackers, and chips are fine in small amounts, but they’re nutritionally empty, so keep portions modest.
The one firm rule with grains and starches: never feed anything moldy. Molds that grow on damp food can produce mycotoxins, a group of fungal poisons that cause serious organ damage in poultry. Stale is fine. Moldy is not. If bread has visible mold, compost it instead of tossing it to your birds.
Meat, Eggs, and Dairy
Chickens are omnivores, not vegetarians, and cooked meat scraps are a good protein source for them. Leftover cooked chicken, beef, pork, or fish are all acceptable. Cook any meat thoroughly before offering it, and avoid anything heavily seasoned or salted. Raw meat carries bacteria risks you don’t want introduced to your coop.
Cooked eggs, including scrambled or hard-boiled, are one of the best protein-rich treats you can offer. Some flock owners worry this will teach chickens to eat their own eggs, but scrambled or mashed eggs look and smell nothing like a freshly laid egg in a nest box, so this rarely becomes a problem. Crush the shells and mix them in for an extra calcium boost.
Dairy is a bit more complicated. Chickens lack the enzyme to efficiently digest lactose, so large quantities of milk or soft cheese can cause loose droppings. Small amounts of yogurt or hard cheese are generally tolerated well, since fermentation and aging reduce lactose content. Plain yogurt is a popular treat among backyard flock keepers and can support gut health.
Foods to Avoid Completely
A short list of common kitchen items should never go to your chickens:
- Avocado skin and pit. These contain persin, a compound toxic to chickens that can cause heart damage and death. The flesh has lower concentrations, but the safest approach is to skip avocados entirely.
- Raw green potatoes and potato peels with green spots. The green color indicates high levels of solanine, a toxin found in nightshade plants. Cooked potatoes without green areas are safe.
- Dried or raw beans. Uncooked kidney beans and other dried beans contain a lectin that is poisonous to chickens. Fully cooked beans are fine.
- Chocolate and coffee. Both contain compounds that are toxic to most animals, chickens included.
- Anything moldy. Mycotoxins produced by common molds on bread, grains, fruit, and other foods can damage a chicken’s liver, kidneys, and immune system.
Nightshades and Citrus: The Gray Area
Tomatoes, peppers, potatoes, and eggplant all belong to the nightshade family, which produces solanine. The green, unripe parts of these plants, including leaves, stems, and unripe fruit, have the highest concentrations. A ripe red tomato or a cooked potato is safe. Green tomatoes, raw green potatoes, and the leafy tops of tomato plants should go in the compost bin.
Citrus is more debated than dangerous. Oranges, lemons, and grapefruit are not poisonous to chickens. Some birds avoid them on their own because of the acidity. In large quantities, citrus can cause digestive upset and loose droppings, but the occasional orange half or leftover citrus peel won’t harm your flock. There’s no established scientific link between citrus and reduced egg production, despite what some older advice claims.
Watch the Salt and Sugar
Heavily processed table scraps tend to be the riskiest, not because of the base ingredients, but because of their salt and sugar content. Chickens are extremely sensitive to sodium. Excess salt causes fluid buildup around the heart, swollen kidneys, and can lead to heart failure. Salty foods like potato chips, pretzels, processed deli meat, and canned soups with high sodium should be offered sparingly or not at all.
Sugary foods like candy, cake frosting, or sweetened cereal aren’t toxic, but they provide zero nutrition and can contribute to obesity. A bite of leftover birthday cake won’t hurt, but keep sugary scraps to a bare minimum.
Scraps That Can Change Egg Flavor
If you raise chickens for eggs, it’s worth knowing that certain foods can alter the taste. Fish meal and flax meal are the biggest culprits, both capable of giving eggs a fishy or earthy flavor. However, tossing your hens a few leftover shrimp tails or a piece of salmon is unlikely to affect egg taste. The flavor change typically requires consistent, concentrated amounts in the daily diet, not an occasional kitchen scrap.
Garlic and onions are often cited as egg flavor changers, but your hens would need to eat very large quantities for you to notice any difference. A few garlic cloves mixed into a bowl of scraps won’t make your morning omelet taste like garlic bread. That said, onions in very large amounts can cause anemia in poultry, so moderation is still wise.
Seasonal Scrap Ideas
In summer heat, water-rich scraps help keep your flock hydrated. Watermelon, cucumber, and frozen fruit are excellent choices. Some chicken keepers freeze chunks of cucumber and berries into large blocks of ice, giving the birds a cool treat to peck at throughout the day.
In winter, your chickens burn more energy staying warm. Scratch grains like cracked corn are a classic cold-weather treat because digesting them generates body heat. Cooked oatmeal, leftover rice, and starchy vegetable scraps like sweet potato peels also provide the extra caloric boost your flock needs on cold nights. Offering these heavier scraps in the evening gives chickens fuel to keep warm overnight.
How to Offer Scraps Safely
Cut large scraps into pieces small enough for your chickens to manage. They don’t have teeth, so anything bigger than a grape should be chopped or broken apart. Scatter scraps on the ground or place them in a shallow dish rather than leaving a pile that can attract rodents overnight. Remove uneaten fresh scraps by the end of the day, especially in warm weather, to prevent spoilage and pest problems.
Keep the 90/10 rule in mind as a daily guideline, not a weekly average. If your flock of six hens eats roughly 4.5 pounds of feed per day combined, that means no more than about half a pound of scraps total across the whole flock. It’s easy to overshoot this, especially when you have a full scrap bowl after dinner. A good visual check: if your chickens are leaving commercial feed untouched in their feeder, you’re probably giving too many treats.
