After my baby chicks woke up I noticed this bump on one of the wings, like on the side of the bone. Doesn't seem to be bothering her at all, but I can see it through her tufts. It's the size of a pimple, it's hard, and its kind of dark on the inside. Overall the chicken is healthy with no other signs or anything. She's eating, sleep, playing and chirping. I'm not sure if I should be concerned with this or not. Thank you for your help!
