I have a pigeon that turned up with a wound on top joint of the wing(i.e. the point at which it folds) and another scrape wound where this touches the chest. I could not work out how she got this wound, it looked like she had somehow scraped it quite bad. It was obviously very sore and although she could just about get up in the air, she was reluctant to do so. Anyway, I gave very little medication, just cleared things up. She has been healing here for about 3 weeks now. The wing is still hanging low, as it did at the beginning, but she is able to fly better with it now. A lot of the swelling has gone down and the skin has healed.
