Either a dog or raccoon broke into the run yesterday, killing 2 hens and badly mauling the other 2. The survivors have large gaping wounds on the backs of their necks and shoulders, lots of skin gone, some tissue torn. They seemed to be in shock so I was scared to handle them too much. I cleaned them as best as I dared with the shower hose since there was a lot of debris ground into the wounds, then covered them neosporin-smeared gauze. Miraculously they survived the night and are looking a bit more alert today, although they won't eat or drink. I'm still in shock myself, it hasn't really sunk in yet that 2 of my girls are gone - but I want to focus on trying to save the others. DOes anyone know how frequently I should change the dressings, and whether there OTC antibiotics I should be giving? Thanks for any and all advice.
