A dog broke through our back fence yesterday and killed 2 of our family pet hens and bit another on the leg. I have the injured hen separated in the garage and have food and water for her in there. I also went to Tractor Supply today and got some blue antibacterial spray and some oxytetracycline to put in her water. I am now reading that it tastes bad and she won't drink the water. There is no sign of infection as of yet, but the skin is broken and she seems in pain. Should I go ahead with the antibiotics or wait to see how she is doing? I am not feeling hopeful she is going to make it, but I want to give her the best chance.
