My rooster is still getting better everyday. I gave him a little bath yesterday, because he was finally ready for it. He's now looking pretty fresh. I've been weening him outside in my garage. Started with a space heater, as it's getting down to the low teens some nights and he was still recovering and transitioning from my 60 degree basement.
He's been off the space heater a few days now, and he's had some good interactions with the hens, so tonight is his first night back in the coop. It seems like he is defending himself from being pecked in the wound. He's posturing the girls more than normal, but honestly it seems pretty harmless. I think worst case scenario is he gets 1 peck too many and has a small cut, and after what he's been through, I don't think that will hurt him too much. My hens are nice and he's a lot bigger than them.
He's grown totally restless of the dog cage I had him in, so I'm happy to return him to the coop. I can't have him free ranging in my garage, unfortunately.
Thanks again for all the help. Seems like he's nearly made a full recovery.
