One of my blue cochin chicks has angel wing pretty bad, and just doesn't grow. She is two weeks old, and the others have their wing, tail and neck feathers, but she just has a few wing feathers. She is half the size of everyone else, but looked the same when they arrived. She did have one eye stuck shut that we fixed, but I have no idea what to do to help her grow. I don't want to make her wings any worse. She's a cutie and can stay as a pet, i'm just worried that she'll never grow feathers...well grow at all!
