We just ordered a metal building for our rabbitry. It is 12x20 and will include a workshop. Once I put in a floor, insulate, and add a window AC unit, we ought to be able to house 24 rabbits in there. The ones outside will be for meat rabbits and there's a chicken coop at the end, partially covered. Wow!
Here is the other side of the mobile home communal area. At the bottom right will be rolling shelves for food storage!
