I have a cream legbar who is almost three years old. She has these black spots and white scabs/scars on her head. We did have a fox who came by our coop this am so also can’t tell if these are war wounds from fox, chicken pecking, or if she has a disease...other chickens in the coop (she has 5 other sisters in a large run/coop) do not have these spots. She is molting right now (poor thing)...I would appreciate any thoughts as I am still a fairly new chicken owner (3 yrs) and have not encountered this before. I am trying to assess if she needs to be isolated from the others.
