I have a young hen who is super aggressive during her molt. She has been molting about two weeks. Yesterday she attacked my lone older hen who is also molting and has arthritis and cannot get away quickly. She put a hole in the older hens head. I have my old girl recovering in a hospital crate in the basement. Any suggestions to deal with this?i am feeding them a higher protein feed and black oil sunflowers seeds plus an occasional scrambled egg but unlike what I have read they are not eating much of their chicken feed.
