I set some chicks under broody hens this summer to get them off the nests. The hens sat on nest for 1 more day then took chicks out and have been raising them. My rooster did not bother them but I did keep an eye on them. Finally moved them to a different pen because of feeding and watering issues (feeder and waterer were too high). I expect little trouble integrating them back into the original pen with the hen. If by themselves the other hens and rooster would kill them.
