I'm a bit biased because I LOVE my bunnies, but you should change that to 100% sure!
Really.. raising rabbits was the very first thing we did and it's taken off quite a bit from there. I still love taking care of them, I even enjoy the bunny chores! But, I may be a bit of a weirdo there.
For the nest box, I put mine in the does cage 3 days before she's due and sometimes up to a week or so before if she's trying to build a nest with her hay.
As for the cages, I use wire and they're a good 3-4 inches away from each other so they can't rip out each other's fur but I've had to put a little board between them. You kind of have to find what works best for you. But like Chickanmanfromarkansas said, it can bring in mites and they pee up a storm and it'll most likely stink pretty good in a short time. Not everyone will agree but I love wire cages and I can even take pictures of my setup to show you, if you want. It's pretty simple and you just put in something (we use pretty big mats) for them to rest on and get off the wire.
We don't do anything with the fur *yet* but my hubby wants to try something in the future. For the meat, we prepare it like you would anything with chicken. You'll be surprised by how much it actually tastes like chicken.. it doesn't have a wild taste or anything to it that would have you doing anything special to prepare it.
I definitely recommend New Zealands! We started out with the standard Rex and then bought two nice New Zealands.. not only are they bigger but they have a much better personality, they're soo much easier to work with too. We started out with 3 does and 1 buck. We brought in 1 NZ doe and 1 NZ buck and we now have a total of 10 rabbits with 3 more cages waiting to be filled after my doe weans her babies
So far we're keeping the rabbits until they're no longer breeding productively. I try to get as many litters as I can a year without wearing out my poor girls. We even started to hatch chickens this year for butchering and the rabbits, even though they seem smaller, fill up the freezer MUCH MUCH faster than the chickens! Getting started was a lot of money and hard work and some setbacks can be heartbreaking (as I experienced this year) but they're more than worth it.
Btw, sorry I was posting on an older thread.. I just love that other people like breeding rabbits for meat!
