If you are just getting set up and are only intending to raise meat for yourself, that's a LOT of rabbits. I read somewhere that 3 or 4 does and a buck can produce in a year more meat than a cow. So, unless you're setting up to sell, or have a HUGE family to feed, your costs to keep all those alive would outweigh any benefit from raising the meat. You could cull what you don't need and eat those, but the older meat isn't near as palatable without stewing. Now, if you can resell what you don't need early on, perhaps it would work well for you. But, too many people get the wrong impression of raising their own rabbit meat by starting too big and getting overwhelmed. They end up quitting and giving it all up. I researched this for nearly a year before committing to going through with it. I bought my rabbits this past August, and actually bought more than I had originally intended. I got mine from someone who realized she didn't have the heart to butcher, and I bought all she had. 6 rabbits, 2 adults and 4 of their juvenile offspring. I culled one of the juvenile males, and kept the other one as replacement. That left 2 juvenile females. The adult female is currently raising a litter. And one of the younger females just kindled yesterday.
So, I am working with 3 does and 2 bucks atm. Had I started with as many as you have in that ad, I must confess that it would have been a hurdle for me. What I have can produce more than what I have need for and I may end up culling out a doe. I'm feeding just me with my rabbits. And even on a light breeding schedule I may end up with more than I can use.
Having said all that, I would be remiss if I didn't express the satisfaction I gain from keeping my rabbits. Each one has its own personality, and it's interesting interacting with each. I am careful to not allow them to be thought of as pets, because that would get in my way when the inevitable comes. But, a couple of my breeders come very close to that designation, especially my working buck, he's a real sweetheart.
Just be aware that your rabbits are totally dependent on you for their very lives. Be careful to not allow that dependence to become too heavy of a chore or you will lose the satisfaction to be had, and they may suffer from it as well. Good luck!
- with just one litter I sold to the local feed store DH's friend owns, I made back my full start up cost. I expanded and just 2 days after I spent $275 on 6 new hanging cages, I stumbled on a deal on CL - four 4-hole hutches, 5 rabbits, a bunch of feeders, nest boxes, and so much more (she just kept adding stuff in! real sweet lady) - all for $250. Doh!
