HELP, we have 9 hens and things have been going well all year until last month when we noticed several of them had bare and bleeding spots where feathers have been pecked out. We consulted out local tractor supply, Agway and other chicken owners and made sure they had a diet high in protein, ruled out mites and gave them things to play with, climb on and scratch grain to keep them busy. In the last week it has progressed severely and 4 of them are bleeding and 1 barely has a tail left and has no feathers on her lower back. We have watched them and I do notice that 2 of them seem to be the bigger bullies but all of them are pecking each other. Blu-Kote and other natural ointments have not deterred them. I am out of ideas, anyone have any other ideas??
