My favorite chick (13 wks) is eating feathers. Not the big ones, but small fluffy 1" long ones. Why is she doing this? Is there something lacking in her food. She is the only one ( out of 8) that I've seen doing this. She is also the only one with an enlarged crop. its not hard, but squishy.. about the size of a golf ball. I have tried veggie oil (her only) and apple vinegar w/mother in their water. She seems ok, eats, drinks, runs around and likes to be held. All chicks have been raised so far on Purina Start and Grow and I plan on keeping on this until the first egg and then switching to a layer feed. The feathers in her crop may be the reason for the enlargement. It is the same in the morning as it is the night before. Tonight I gave them speggetti, one at a time, each came over for their treat, but she had one and went back to her feathers....don't know how many she eats in a day. Anyone else have chicks that eat feathers? She is an Easter Egger.
