My BSL hen has been progressively getting more and more bald over the past few months (I believe she's about 2). She is the favourite hen of my roo, but her feathers did not seem to start to grow back when I separated her from him for a couple weeks. She is bald on the back of her neck, her back, the tops of her wings and a large area around her vent. The bald areas do not look sore, but do not show regrowth and she hasn't even slowed down on laying eggs. Also, the coop is full of DE and I have seen her dust bath in it, as they all do from time to time. None of the other hens have this. I wonder if the back and neck feathers are from the rooster's affections and the vent feathers are from her because I did see her pick at herself one day before she went and laid her egg. Any ideas??? She's very sweet but UGLY!!
