2 X 3 these are part 1. There's a set of these moble units that we've made a shelving systen for, to stack them. So for cleaning I can slide a pen off the shelf (the quail stay in an old birdcage while I clean), clean disenfect and change trays, then set it back on the rack. I have plans i drew on graph paper, but they don't post well here.
those are really nice breeder cages, think you could find it in your heart to throw a couple more pics up to help an amateur out?
