Backyard chicken keepers often wonder which vegetables are safe for their flock. A common question is: can chickens eat green onions? The answer is no. Chickens should not eat green onions (also known as scallions). Onions, whether raw or cooked, contain compounds called thiosulfates that can damage red blood cells and cause anemia in poultry. Even small amounts over time may reduce egg production and harm overall health.
While green onions are unsafe, there are many other safe vegetables and treats your flock can enjoy. In this guide, we’ll explain the risks of feeding onions, what healthy alternatives you can use instead, and review the best safe snacks for chickens.
