My neighbors dog got into my run and got one of my chicks that have been with the flock outside for almost a week. The chick is alive and doesnt appear to have broken bones but the dog tore the skin off of her neck. I put veticyn on it and have her in the house in a warm quiet spot. I gave her water with electrolytes as well. Is there anything else I can do? I have penicillin and am wondering if that would be worthwhile to give her as I am concerned about an infection.
