I had to remove an injured hen from her flock because she was picked on so badly that she had a bloody head injury. She has been away from them but in a pen right beside them where they can see her, for several weeks. We had 10 in the coop at the time of her injury, but have removed 4, so there are 5(4 hens, 1 rooster) in the coop I need to put her back in. Any suggestions on how I can place her back in the coop? Should I put one hen in with her for several days, and then introduced the two at the same time, so she won't be singled out by the others?
