I had planned on Rabbits for here, but in TN they have to be USDA inspected or sold as pet food. You would be amazed at the number of folks buying pet food who don't have pets. Same with raw milk if you don't have a milk share.
The laws vary so much from state to state. In Florida we could sell live rabbits, the customers had to butcher them. We couldn't buy raw milk. And a lot of canned things could be sold, but nothing with tomatoes in it.
I haven't really checked on the laws here in WY since we're just keeping a small flock of chickens for ourselves. One thing I have read is that you have to have special permission to raise quail.
