Some dogs got into the coop and killed all 15 chickens and 1 duck leaving my Mallard the only survivor.. His wing is gone, down to the bone and some meat.. I don't want to give up on him, hes eating and drinking, and getting in his water bowl.. The Sherrif told us to put some type of oil to keep flies on so my brother did so. I'm not sure what to do from there.. hes out in the coop alone missing his best bud
