My Cochin hen has 4 babies, 1 wk old, in my new coop with a 14 ft. run on it. Mama has been taking babies out since day 2 into the pen during the day. I'm new at this so was wondering, when do you let the hen & chicks start free ranging with the flock? I know its way to soon now but I don't see much re chicks with a mama hen and what happens on this site, everything seems to be the incubated chicks without a mom. I'm afraid to let them out for a long time due to poss. predators, etc. but know eventually I will need to. Any advise for a 1st hatcher, both mama hen & mama owner? Thanks - Sharon
