lump on wing
Hi, my cockatiel has a small (less than pea-size) hard lump on the middle of his wing. Usually it is covered up with feathers, but it is actually bald there. I've had him for over 5 years, and that lump has been there at least a year or two. I don't really remember it not being there. He doesn't seem bothered by it at all, but it seems abnormal to me so I thought I'd check up on it.
