We are building a hood house for our chickens. It will be moved every day to fresh pasture. The hoop house will measure 7 ft x 6' 8" and it will have a coop attached to the back. We haven't decided on coop dimensions yet, but it will not take up any of the hoop house area. My question is, approximately how many standard Ameraucana hens will this comfortably house? We will not be keeping a rooster, and hens will be layers only.
