That’s exactly what happened eventually when she’s stronger and walking better I will put her in a separate coop with separate run in the chicken yard. Someone suggested getting her a younger docile hen to make friends with her and try them together with the flock. I will definitely try that. She is low in the order because she was originally introduced as a single hen. My others were introduced as pairs or more raised/brooded together. She was raised as a pair by my daughter but one was a roo we rejones, so she went into the flock as a single. I have two reds. Every red I’ve ever had was an a**.You just never know how they are going to act. I try not to remove a bird out of sight unless I absolutely have to. If I feel one needs some type of protection, I set up a kennel inside the run so they can all still be "together". If it's a rooster then moving them around is not so bad, but for a hen especially if she's lower in the pecking order it can be brutal trying to get them back with the flock.
