Thank you Porkpal.
Sounds like you have a great setup!
It sure would make it easier if we had that other coop up and running; plus our chickens have complete free range to go wherever they want, with no fenced in area. Last time, when we brought the Amaraucans in, it was in January and they were already about 6 months old. We just put them in there with the others. They had been living in a small cage, never free ranged, so they didn't leave the coop until around March when the rooster, Captain Jack brought them out. It all worked out.
It's possible that Captain Jack will take charge again if we put the others in there...
There is a small caged area off the coop if I could figure out a way to use that to keep the chicks inside but still let the older ones out. Hmmm!
