I hope I did the right thing, what do you guys think? A dog got to my chickens tonight and wounded one, killed another. The wounded one was unable to stand when I found her, I picked her up and put her in a warm dark space for about an hour, and she regained her footing. I gave her a thorough once-over and found a couple of small bite wounds and one large tear in her skin under her wing, the hole is about 3 cm across. Nothing broken and no apparent penetrating injuries. I opted not to stitch the big wound, I plucked what feathers I could from the edges, rinsed it out with saline and sprinkled some oxytetracyline powder on it. I gave her a shot of Tylan and put her in one of the nest boxes. Should I have stitched her up?
