Here is some free advice from someone whose made mistakes. The main thing about rabbit housing is keep them dry, out of drafts in the winter and ventilated in the summer, and keep them safe. You have seen several very nice set-ups and there are many more out there. However, if you want to start with meat rabbits this is where I would start. First, look for used cages at flee markets, yard sales, Craigslist, etc. I either bought or had gave to me seven 24" by 24" cages for a total cost of $12 dollars. If you find that these are too small for your meat rabbits, like I did, then you can easily combine three 24" by 24" and make two 24" by 36" inch cages. I used some J-clamps, J-clamp pliers (which you will need if you have rabbit cages) and wire cutters. I had purchased some nice big cages from the local farm store and wasted my money. My point is, think outside the box. Second, do some research before you buy your rabbits. Two does and a buck will produce plenty of rabbit meat for one family to eat. Buy white rabbits if you think you may have trouble killing them, it's easier to process if they all look the same. Third, do not spend a ton of money for your starter stock. If you do not plan to show them, do not buy show quality. Go to a local swap meet or find someone (Craigslist) who has good rabbits and buy your starter does from them. I recently bought two replacement does and spent $4 apiece. They were about 12 weeks old and are cross-bred. I will finish raising them and when they are old enough (5-6 months) I will incorporate them into the rotation. Buying young gives them time to acclimate themselves to their surroundings and you won't get "took" by someone trying to pawn off their old stock. I sold a young doe to a guy back last year for $5 dollars because she didn't raise large enough babies. I was upfront about why I was selling her. This same guy had that doe (now two years old and worn out) at a swap meet a few days ago trying to sell her as a young doe for $10. Fourth, don't over breed your does. Your does will last longer if you give them a break of 1-2 weeks between weening and re-breeding. The temptation will be to re-breed as soon as the babies come out of the nest box, don't. Fifth, do not allow yourself to fall into the temptation of getting or keeping more does than you can handle or feed. You will have thoughts like: "people will surely buy my rabbits", you may sell some, however, your freezer or your cages will get full in a hurry. Sixth, some people will criticize you for killing "poor, defenseless, cute" bunnies, I tell them that when they become hungry enough, they can join me for dinner. Finally, remember, the purpose of "meat" rabbits is to have extra meat on the table at a minimal cost, shop around for feed, supplies, and stock. Keep your costs down.
I hope this helps.
