I think that raising livestock almost always involves baptism by fire and lots of failures, if you stick with it longer than a year or two anyway. Even folks that grow up in ag often find things to be different once they're out on their own, making their own decisions. I know that my close rabbit breeder friends and I - among three of us, we have approximately 70 years of experience - frequently have reason to comment that there's
always something new (and usually not good).
The silver lining to coming out the other side of failures, is that I really love it when others can learn from my mistakes.
You'll get there too!
I've found the very best resources to be other breeders, so if you can find some of those to stay in contact with, that's ideal. (I'm thinking personal contacts, but this forum is also an outstanding resource in that regard.) When I sell anyone rabbits I try to make them understand that there is no amount of questions that will bother me, and I encourage them to ask, since I really want them to be successful (see above about learning from some else's mistakes!). If you can strike up a relationship with your rabbits' breeder, that would be great. If he/she raises them for show, ask about when the next show is and go walk around and talk to the folks there. I don't know specifically about OK, but most rabbit folks I've met are pretty keen to talk about their rabbits.
For printed resources regarding general rabbit care, some decent ones are:
The ARBA's
Official Guidebook to Raising Better Rabbits & Cavies
- You get this when you join the ARBA, and I suggest that's worth doing. It's not expensive, and you also get a bi-monthly color magazine full of interesting and useful information. It's not just for people raising rabbits for show. Find out more here:
