I'm integrating 5 week old chicks with my adult flock and have received great advice here. So far we've let the chicks out in the run with the adults where they have a place to keep to themselves. It's worked well. 3 of the hens will peck at the chicks when they get too close, the others don't seem to care, and none chase the chicks down. I haven't yet let them out inside the coop as there is less space to run around in there. I just realised though that I haven't really picked up on how long it is normal for the adults to peck at the chicks... Will this continue until they start laying or will it cool down sooner at some point? I haven't dared yet to leave them unattended although everything seems to run smoothly so far.
