Found a bush dove unable to fly properly. Her right wing is very swollen at one of the joints and rather warm. She can flap it, but can't bend it, or stretch it. There's no open wonds or visible trauma other than the lump. Everything else seems fine. Whe she walks it droops. I'm keeping her in a dark basket and offering her food and water out of bottle lids. Any recommendations as to how else I can help? I think it's Brocken or fractured. I'm not sure.
