I have a pullet who seems to be very popular with the roo and because of this she has lost alot of feathers on her back. The skin looks very dry now. There is not any bleeding yet and I would like to know what I can do to prevent it. I think I should probably isolate her, hate to pen her up when all the other chickens have free reign of the yard. Is there any type of slave to put on her feathers and also can anything be done to prevent it from happening again?
