My little rooster's top beak appears to be detaching. He had a very severe injury last week. My son accidentally stepped on his head and half of his crest was ripped from his head. I at first had no hope for him to survive, but an hour and a half after his injury he was still alive. I called my friend who frequents this forum and asked her if she had ever heard of someone sewing a crest back on. She said she had. She came and reattached his crest. He was in severe shock until about 3:00 a.m. the next morning when he managed to open one eye. By day two he was crowing and by day three walking around almost as normal. We have kept him in the house to recover and he only goes on surpervised trips outside. His crest looks great, but today it looks as if his upper beak may be detaching. I think it may have been severely bruised. We were concerned about it at first, but he immediately began eating and using it as normal. We could see what looked like a crack along one side, but it was never severely out of place. Now his beak looks like it is separating or may completely fall off. What should I do?
