I am the owner of seven hens, and almost all of them are missing feathers in patches somewhere on their bodies. They are rather unsightly (poor girls!) and I don't know how to deal with their hen pecking behavior. They are kept in an enclosed pen which is not very large, but they certainly are not cramped! I have checked, and they do not have lice or mites. However, I believe the reason for their feather loss is because they are bored and they pick on each other. Is there some way I can put a stop to it? They will be rather chilly this winter if they keep picking off their feathers!
