Can Chickens Eat Vegetables?

Yes, chickens can eat many common vegetables found in gardens or at the grocery store. Vegetables provide important vitamins, minerals, and nutrients in a chicken’s diet. Here’s a list of some of the best vegetables for chickens.

Leafy Greens

Lettuce, kale, spinach and other leafy greens are excellent sources of vitamins A, K, C and calcium. Chickens enjoy whole leaves or chopped greens mixed into feed. Avoid iceberg lettuce which has limited nutrients.

Root Vegetables

Potatoes, sweet potatoes, carrots, beets, turnips and yams provide beneficial fiber, beta-carotene and vitamin C. Cook starchy veggies to break down complex carbs.


Zucchini, pumpkin, yellow squash, butternut squash, carrots, turnips, broccoli and foods are high in vitamins A, C and fiber. Squash seeds also contain protein and omega-3s. Slice large pieces for easy eating.

Cruciferous Veggies

Broccoli, cauliflower, cabbage, brussels sprouts and bok choy are loaded with antioxidants, vitamins C, E, K and folate.


Bell peppers, chili peppers and sweet roasting peppers add beta-carotene, antioxidants and vitamin C. Just go light on hot peppers.

Green Beans

A favorite treat packed with thiamine, vitamin C, iron and calcium. Offer dried or blanched green beans.

Sweet Corn

High in fiber, lutein and vitamin C. Give chickens fresh or thawed, cooked corn kernels off the cob.


When feeding veggies, introduce new items slowly and chop larger pieces into bite-sized bits for safe eating. Avoid raw potatoes and rhubarb leaves which can be poisonous.
