I started off with a lone coop that I had purchased. Chicks get to explore: Dog wonders if he'll be kicked out of the house soon: I heard sand floors were good so I went with them. But what about the run? I decide that this coop was just not big enough. EXPANSION! Progress has been maddeeee (in due time) Because I am dealing with liver rejection, a few friends came over to help make thins happen! We are now at a nearly completed coop!
