I have a young Barred Rock pullet that had been pecked by her flock mates. Her wing was terribly bruised and wounded. I isolated her and treated her injuries and now she's almost ready to go back into the flock. How should I get her back in....? She is young, three months, compared to hens ranging from 7 months to three months. I could put her in a cage in the larger coop, if that's the best way to do this. Any advice?
