I have about 17 hens and 1 rooster in my coop and in the past month or so they are all picking on eachother worse and worse each day. I had to remove one hen from the coop because she almost had no feathers left. I let her stay in my garage until her feathers grew back and I put her back in the coop. By the next morning she had her whole backside pecked out again! Now it seems like every day each chicken has less and less feathers. I tried the "blue lotion" on the bare spots but it hasnt seemed to deter the behavior. My beautiful chickens look horrible and Im sure the bare skin in February cant feel too good either! This cant be normal, any ideas?????
