Hi! Recently, my Irish Wolfhound attacked one of our chickens. It wasn't out of aggression, he scared her, she ran, he chased her down, picked her up with his mouth and shook her. I yelled at him and he immediately dropped her but upon picking her up I saw an open wound on her back from his teeth, and you could see her internal organs. I did not think she would make it through the night but she somehow did. I have her in a covered cage with water, food, and a heat lamp. She is now acting like normal but still with the open wound. What do I do?
