Help! My dogs somehow got into my coop and attacked two of my chickens, one was dead (No body found just feathers and feet) but one is still alive with alot of injuries, wing seems broken and lots of blood and wounds to its back, it's legs and face are ok. It's not letting me post a picture but should I try and treat the injury or just put it down, I have it separated and have treated her with vertricin. I'm such a mess over here! Help!!
