Do eagles eat chickens?
Chickens are not the preferred food of eagles. American (Bald) eagles eat mostly fish and golden eagles eat mostly small mammals like rabbits and squirrels. I suppose if an eagle was very hungry and could find nothing better, he would indeed eat a chicken. And who would blame him?
Chickens are used to produce eggs and meat for humans to eat, and there tend to be a lot of humans to feed on this planet. Bald Eagles are wild animals, and humans have infiltrated their environment so much that it affects the number of birds there are around. Some folks see them as pests because they can catch and kill other birds (like chickens) and fish.
