One of my girls has been getting her feathers pulled out by a couple of the other girls for the past couple months and I'm not sure how to stop it from happening. It's a patch on her back right in front of her tail (not from being mounted, we don't have any roos) and it leaves her bald until the new feathers start to appear, then they are pulled out again. I've identified one of the bullies and am sure there are others, what do I do now? I don't want her to end up permanently bald, she is a gorgeous little Jersey Black Giant with the sweetest, shyest attitude. Any advice/solutions?
