We bought our rabbits from a local breeder. We keep them in four separate cages. Tai built the hutches from some 2x4s, crates, screen, wire, sheet metal roofing, an old grill, nails and a staple gun. Our original cage had just two compartments: one for the does, one for the buck (you have to keep them separated). The door of first two cages is made out of an old grill. It makes it look like bunny jail, but it is much more effective than the screen doors on the two new cages. Underneath the cages, we wedged the sheet metal roofing so that it is a bit easier to gather the rabbit waste to add to our compost for the garden.
