I’m worried about one of my black stars I noticed last week a lot of black feathers around the yard and thought I’d lost one to a predator but they were all accounted for. So after inspecting all the black chickens I found the culprit. I don’t know if it’s bullying or what I don’t think it’s he right time for molting right before winter. Is there some kind of deficiency she’s not balding anywhere but when I tugged gently on a feather near her leg it popped right off with no resistance now I noticed some tail feathers are missing. What is going on?
