So, when my button started to get his "grown-up" feathers, he had this funny little twisted feather on top of his head, it looked like it was backwards. When that feather fell out, he started to get a bald spot. I just let it be, because I figured it would heal itself. Well, when I got home from work today, this is what I saw. There is nothing in his cage that he could get cut on, that I know of. He is also alone, so it is not a pecking problem. Any ideas? Is this maybe a skin condition?
