I've got a flock of production chickens that are getting old. Its 10 hens. One of the hens can't get up on the roost & the girls want to kill her. I separated her. She still eats good but I can't keep her like this. Should I let her get her strength back & put her back with the flock or just put her down? I hate this part of raising birds but I know I have to do the best thing for the flock. I think they will kill her. They are just doing what they do. Getting rid of the weak. She, has done her job. She layed a ton of eggs & I will keep her but I can't keep her isolated she will have to live with her flock but seems like they want to kill her & I know they probably will.
