I've let the mother hens do the hatching and raising lately. They do fine, but the issue I've run into is i had one batch that only one lived to hatch date, making her a loner. Well after the mama was done with her, little by little my flock turned on her and try to kill her off horrifically. So I put her in a cage they can see her in without getting to her, did that for a month, tried again, within an hr I had to rescue her from over half the flock chasing her. So now I've put three of the nicer chickens with her for two months. They don't peck her or bully her. But she's like anxious Annie, scared to death of all chickens and people. If I add all of them into the flock again, I'm sure they will still isolate her, because she's so skittish she won't be able to integrate. I hate this so much she was my first grandchicken
