Wondering how long most people keep the chicks with the mom. i have a showgirl mom with her 13-week-old chicks that i moved into another pen with some young hens several weeks back. After some pecking, they all seem to be getting along okay. But i also have two other moms with 7-week-old babies and one with 9-week-old babies. They both seem pretty done with motherhood. i'm pondering putting the moms back into their old pens and merging the two chick groups. i was just wondering what other people do, especially those who breed on a regular basis.
