One more thing. You don't have to have a bottom in the coop. When it comes time to move the chickens I just start moving the run units and the chicken come out and tend to follow me around. When I have several of the units together I just pick up one of the boss chickens, take her to the new setup, put her in and then just sit there and wait for the rest of them to come on over. It's the funnest part of moving. If you raise them from chicks and feed them by hand a lot, they pretty much go where you go.
