One of my bantam roosters was attacked by a dog two days ago. He has been favoring his right leg since then. We don’t see any wounds, but other than brief moments of standing and limping around, he mostly wants to lay down and rest. At first he couldn’t even tilt his head down to eat without falling forward, and now, he can stand a for a few seconds and eat scratch off the ground so he does seem to be improving. I’ve been bringing him inside during the day. In the evening last night, I brought him outside with the other chickens and they don't seem to be bothering him. He seemed happier with his flock. He did painfully limp his way to the coop when everyone else went and I let him sleep in the coop overnight. He is eating well when I feed him, but I haven’t seen him drink on his own and I have been giving him water with a syringe. Should I put him outside with the flock more often and let hIm heal on his own, or continue to keep him inside most of the time? Should I put him in a sling? Any advice is appreciated.
