I want to get all of my chickens to live in the same coop. Every night they always go back to the coop they have been brought up in. I would like to switch the birds and put them in different coops. The big girls in the little girls coop and the little girls in the big girls coop. Has anyone ever tried this. We are going to build a new barn with a new coop attached, but I would like them to get used to sleeping together. They currently lay their eggs in each others nest boxes. The big girls are 2 yrs old and the little girls are 5 months old. They are all about the same in size. There are pictures on my BYC Page.
