I have been researching coop design quite extensively over the past few weeks. Just bought four chicks on Saturday and I am going to start building housing soon. I have a smaller backyard and was throwing around the idea of a stationary coop with a moveable run/ chicken tractor I could rotate around the yard during the day while I was away, and moving run back to coop at night, giving the chickens the security of a more substantial coop. (I hope that makes sense.). Thoughts from more experienced please!
