Our rooster was a little too aggressive with one of our hens. He tore the back of her neck open, a zigzag laceration. We cleaned it out and put neosporin on it a couple days ago and put her in her own little coop to heal. Looked good yesterday so we put her back in the large coop last nigjt. I went out today and her neck is tore open again. Any ideas what to do for her injury and her safety?
