Interesting comments - thank you, all. I remember reading an article about Joel Salatin's pastured poultry model, and it made a brief mention that he also used a similar arrangement on rabbits - showed a not-very-clear picture, and it appeared to be the same type of roofed, portable pen he uses on birds... can't find any other info about it, but am wondering: do you think with moving it every day, it would keep the rabbits from burrowing? What about the idea of individual pens for each buck, also? I need to figure something out, because it just doesn't sit well with me, having them in small confinement systems {cages} from birth to butchering. I'm hoping someone here has already had experience at this; if not, I'll have to invent a system.
