If I ever get that close, and the Mrs allows it, here is my plan: I will be getting a business license so I can conduct business within the city limits. Then I plan to reserve a table at the local farmers market. I feel kind of lucky because where I live there is a farmers market 5 minutes from my house, and another one within a "frisbee throw" of the University of Alabama campus, which is a 15 minute drive. I've been to both, and none of the farmers knows of anyone who raises quail. Each of the farmers markets are open from 5 am till noon on Saturdays, and if I'm lucky, I'll only have 3 or 4 cartons for sale. I'm not going to price them so I can make a killing; I will sell them for a reasonable price to help pay for feed. By then, I'll have some egg cartons for quail eggs.
That is, of course, if the "Mrs allows it". When I first mentioned the idea of raising quail, she was "more impressed" by the benefits of the eggs than anything else. She even devised a plan where she would find out the quail egg equivalent of a chicken egg so she can freeze the eggs in containers for future use.
