I've had momma and her three chicks enclosed in a smaller section of the main pen with chicken wire. The chicks are two weeks old. The main flock which momma is/was part of is 15 birds and they've gotten a good eyeball on the chicks for a week. I have a need for the smaller pen momma and chicks are in (it's 3.5 x8 ft or so) can I let momma and chicks out with adults or am I asking for lots of trouble?? Thanks, Keystonepaul
