There certainly have been discussions on this, but I can't seem to locate them. I am a chicken person who is fascinated by all the interest in quail. I know you can eat the tiny eggs, but why not just raise chickens if that is your motivation? Do you raise them to stock the freezer, or is it for hunting purposes? I'm lead to believe they rarely will naturalize. Maybe its just for the fun of it, it does sound like fun.
