I had a cockerel (Sir Poops A Lot) he'd been attacked by the others, when I took him from his chicken mama, he was a bloody featherless mess, I bought him home, bathed him, put medicine on him, he stayed in his crate in my brooder room, only company was a batch of chicks in the tote on the other side of the room, I kept him in that till the open wounds healed and transferred him to the TSC coop I have in the yard, it was a look but don't touch.. he grew up to be a beautiful Roo when the feathers came back in. I personally don't see a issue with him being in a look but don't touch till the feathers are back, he'll get use to the flock and the flock will get use to him.
