They are molting. I have 23 hens. They all have bare backs. They are eating each others new feathers. It gets worse. They keep pecking at each other until they have bloody holes in their back. I have 3 cases so far. I need advise on what to do. Idon't now why they do it. I now i have to isolate them. Problem is how? I can't put two in the same cage they will peck at each other. So how to isolate? I am worried about space because over the coarse of the day when I come back home I don't want them to be sitting in their own crap.
