I just got back into Coturnix again, after a 2-year break. My 13 quail are 11 weeks old (in a colony pen) and I have yet to get a single egg from them. What is going on? They are on Gamebird Breeder feed. I have been waiting and waiting, and nothing yet! I know when I had quail before they were always laying well by 8 weeks. Is it too hot for them, maybe?
