Hi, two days ago I found my one year old cayuga in her pen with her wing hanging down. I took her inside to examine her then discovered that she had somehow been attacked all of the feather where her wing connects to her body were gone and she had a cut that was oozing. I've been keeping her inside washing her cut with saline spray, putting neosporin on her cut, wrapping her wing in place with gauze, and gave her anibiotics I had left over from the vet. I thought she was getting better but when I just washed her wounds I saw that the skin near the cut has turned a greenish color. I'm very worried for her now. Does anyone know why this happened and what I could do to fix it? Thanks
