For better reintegration you could just have her with one of the more docile hens for some days and then add another and reintegrate the threesome after 7-10 days.This way she will not be the odd one out but part of a threesome.The limp isn’t visible but the flock is chasing her. I’m allowing it if I see it because she’s probably being reassigned a pecking order position. But I see her hiding so much I’m not sure she’s eating. Tonight she’s in a nest instead of roosting. She seems ok otherwise.
