Very interesting to read about chicks adapting to the coop. My eight chicks are five wks. old and I hope to move them out at six wks., temperatures permitting. I will move my brooder to the coop w/a heat lamp where they can get acquainted w/the two older hens and the rooster for a week or two through the wire mesh. The chicks will have their own door and yard to play in while visiting w/the big kids through the wire mesh. I'm worried that the littles will get beaten up by the big kids. I've gotten so fond of them and feel very protective! Like a mother hen, I guess. I hope to hear your experiences w/this situation. By the way, my alpha chick is an Ameraucana and she really bosses the R.I. Reds, the black Australorps and the Maran. She will probably have to learn a lesson in pecking order when she joins the big girls.
