I hadn't been out to my coops in a couple of days, so I was startled to find one of my little Silkie hens with these wounds on her wings (photos attached). We have a rat problem which i'm addressing by removing feed/water at night and setting zappers all around. Could rat bites and other hens pecking have caused these wounds? I'd also like advice on next steps (separate her from the others, euthanize (hopefully not), etc). She has an almost identical wound on her right side, as well.
