I rescued a baby swan (someone brought him to me after his parents were killed) when he was a day old. He has been doing fine (he's 13 weeks old now), and my female duck's have taken him in with no problems. He was doing fine then something happened to his leg. He can't walk on it, but can stand and butt scoots around. Can I give him Asprin? I give my chickens 1/2 of a 81mg Asprin if they get injured, so I wasn't sure. I've been keeping it wrapped with Coban, and that seems to help his pain some. Thanks!
