Hi! I have a flock of seven that I believe generally gets along. Except, recently, a few of the younger ones have been picking on one of the older ones. She has a few odd bald-ish spots on her head, but she has also been molting. I'm not sure if this is molting or bullying. She is very skiddish around her sisters that pick on her. I'm not sure if this is just sisterly squabbling or something more. Please help me!
