I am considering raising quail for meat. 1. Cotournix quail seem to be the best for meat--correct? 2. How well do they do in cold winter climates. 3. Do they set their own eggs--hatch and raise their own young? 4. What type of housing/special requirements do they need? (for hot summers/cold winters) 5. Anything else I might need to know/consider before ordering some? Thanks!
