hi there.. I have a lil rooster boy close to one year old, that's started to loose his feathers, first down the front of his neck and now onto his chest. His skin looks kind of red or irritated. He gets scratch and layer crumbles and healthy snacks. No one is picking on him tho I have noticed some gentle picking on him from his girlfriends.. Not sure if that's the problem or not. I'm wondering if it could be stress related from some frostbite he had gotten and is recovering from? Not sure what to do. Any advice is appreciated. He just so happens to be my favorite also. A little sweet heart. Thank you!!
