I have a OE rooster who is about 18 weeks old. He is crowing and starting to try to mount hens. He seems to have zeroed in on one particular Australorp gal who is about 21 weeks old. She runs like crazy from him and I've seen him try to mount and then tumble off over her head. Just today when I went out to give some treats, I noticed that the area behind her comb is almost completely bald and as red as her comb. There is no obvious blood. I covered the bald spot with blue kote. Would you do more? Will they "work it out" or is she in danger. The last time he went after her she squatted and stuck her head under some foliage. I've had chickens get pretty bald backs from roosters holding on, but never experienced this with the head. Please advise!
