We have a PR rooster and 3 PR hens in our original flock. We also have 17 chicks (7 wks old) who are already in the large new coop and run. We are planning on moving the older flock in with the chicks in the larger area and using their small coop and run as a grow out pen, broody pen, etc. Everything that I've read gives suggestions on adding chicks into an established flocks's territory. I will be adding an established flock into the chick's territory. Does it make a difference or will it be the same process?
