Sure you could do that. We have a local livestock auction and alot of time towards the animals are going dirt cheap, there are people buying full size rabbits at 1 or 2 $ each. That would be a great deal if you just wanted rabbit to eat. The grow out time depends on the breed and how big you want them. Some rabbits will fight/ chew on each other others you can grow out together. I would have a cage per rabbit just to be on the safe side.
