My 4 year old buff orpington was attacked by the neighbor's puppy today. She is missing all her butt and tail feathers and has cuts and blood in that area. What can I do for first aid?? She is eating, drinking and running around in the yard with the rest of the 10-bird flock and seems OK otherwise. Do I have to worry about the other chickens pecking her? She is the biggest and most dominant one out of the flock. Please let me know what I should do. Thank You!
