I looked up the food and ag code here in California. I still had a few questions, but I now know what NOT to do and it also points me in the right direction as far as what permits I might need.
I live in big time farm country and most of the time when I try to be legal and get permits, etc., the inspecters kind of roll their eyes at me and don't want to be bothered with my pindly little operation. I have an egg-handlers permit and my bees are registered but on both items I was told flat out that I would never be inspected unless there was a complaint. But that might be different wherever you decide to settle in.

It can be hard to get info, even from the person who is in charge of your state's program. A new food coop was opening in my town, they had a meeting with some state people to let the producers know about state regulations. The meat guy didn't really seem to know much, you are able to process 2000 chickens per year, to be sold only directly to the consumer. Rabbits are supposed to be processed in a state inspected facility-but they only have 6 inspectors for the state. He seemed to be saying'do want you want'. Around here you can buy a dressed rabbit for $6. We can sell them for pets for more.
