My dog got out of the fence yesterday and got one of my chickens... She has a pretty deep wound but she will live I believe if it doesn't get infected and nasty. She hurt her leg or foot I imagine it's broke and she has her foot curled up and today I noticed it has gone black. What's the best medicine to use on this deep wound and what should I do about her foot? Do you think it would just be best to kill her and take her out of her misery? Please help this is my first year with chickens. I also have her in a dog cage with shavings to keep her from getting dirty and as of now I just put bag balm in the wound to keep dirt from entering! Please help!
