I have a mama chicken that hatched out 3 peachicks and has been raising them in a pen for the past 10 weeks. She has most likely had enough of this and wants to get out of the pen to free range with the other chickens. I let her out a time or two and she comes back in at night to roost with the peachicks, but the peachicks cry for her most of the day while she is out. Are the 10 week old peachicks old enough now to stay by themselves? I have read that the peahen usually stays with the chicks from 6 months to a year, but of course a chicken hen is ready for freedom at about 8 weeks or sooner. Any advice? Should I let the mama hen go back to being a chicken??? Or keep her with the peachicks whether she likes it or not???
