I think i found out what's wrong. It makes sense bc she's the top dog in the pecking order & the others don't peck her.
I'll have to do some research on that vent gleet I've never heard of that. I'd suspect being picked on too but I've sat & watched & she runs the roost. Is vent gleet serious?
Does anybody know what's going on my girl? This started several months ago but I thought it was bc she was going thru a molt but now she's got a spot on her chest. I've treated the coop for mites/lice & there are 13 other chickas that r fine & recently molted normally as she did too everywhere...
