Last night I noticed my black copper Marans pullet had a small lump on her head. I thought maybe she got stung by a yellow jacket when she was free ranging, but now I think she has some sort of infection. This morning I washed it because it look like she had a lot of feather shaft shedding around the area. I don’t know if this is some sort of infection, but it looks like that to me. Please if anybody out there knows what this is and can tell me what to do it would be greatly appreciated! Here are a few photos.I don’t know if it could be related, but about a month and a half ago I had to take her to the vet because she had an eye infection.
