I need to go out and sort of level the area where the coop is going, but do I need to do anything like add sand, etc? It's going on an area that we had topsoil laid a couple of years ago, but we put a garden in and made some mounds I need to flatten out. It's all weeds now Also, you put shavings down on the floor of the inside of the coop right? But not outside in the run? I'm so confused. Heh.
