I came back today after going away for three days and found that my chickens had been attacked while I was gone. I have two coops, one with my 2 older chickens and one with my 2 silkie hens and all of my young chickens. The second coop is raised with a covered pen and I had covered the gap under the coop with plastic barrier. Something had chewed or clawed through the barrier and killed 5 of my young dominiques and one older hen. I found another one of my Dominiques drinking, injured, but acting normal. I brought her in and clipped the feathers around the area. Her wing had been torn off and there is considerable injuries around it. I washed the wounds out with water, then hydrogen peroxide. Then I put antibiotics on the wounds and covered them with gauze, then wrapped it with ace bandage. She doesn't seem to be in pain, but she thrashed and yelled when I washed out the wound with hydrogen peroxide, because it stings. She was drinking when I brought her in, but I haven't tried to give her anything else since, I've been treatin the wound. How should I continue to treat her wound, it's pretty bad, I don't want it to get infected either? If she recovers, will she be ok without a wing?
