For now, you can just scour around for cheap/free supplies to get their pens built. I've been doing the same, I've got the new garden, the turkeys (now ducks) and tons of chicken peeps to sell and more hatching, PLUS 114 button quail eggs that should hatch this week. WAAAAYYYY too busy to be thinking about rabbits, but of course, I AM thinking about them. So, to keep myself content about the rabbits until I can actually get some, I've just been looking for great deals on caging materials.
