Our rooster is acting perfectly normal. Normal for him is scratching, pecking, and mounting the ladies. However, his feathers began looking very ratty. He looks furry? Not smooth. His neck, back, and wing feathers are all broken and frayed. The other day I noticed his vent was bare, raw, and scabbed/bleeding. It looks very angry and is absolutely not normal. I can't find any mites or louse on any of our birds. They have access to clean food and water daily and their coop is cleaned regularly. I have 10 hens plus him. He appears to be the only one affected, although some of our hens have the "saddle" from him getting at their backs. I already have one chicken inside the house that is recovering from a hawk attack so I don't have room for him too! What is this horrible looking thing and what can I do to help him??
