We have three coops now. Besides our main coop, we have a rabbit hutch as a retirement coop for our two oldest chickens who are bantams and eventually started getting picked on, and one is for anyone who needs chicken jail. I wish that we had this set up though! Then they are at least kind of together. I agree that it would be especially nice with hatching and integrating chicks into the flock. I wish I had thought of this when my husband was building my large coop!
