I noticed today that one of my week old chick has a bald spot, almost looks like small bump at her wing joint, I am not sure if she's been picking at it, or the other? I have not seen any others doing it and the way it is under her wing, makes me think she did it to herself. She's using the wing just fine, flapping and stretching it out, she freaked out a bit when I was holding her and trying to get a closer look at it, not sure if it was hurting her or just was just freaked about being handled. Anyone know if I should be concerned, is it common? what can I do to discourage her from picking? Thank you!
