i have 4 coturnix quail(3 hens and a rooster) when they wer about 5 weeks i looked into their small pen and there was 3 eggs. a few days later i moved them to a new pen and got about 6 more eggs, since then i added a red light that stays on continuosly. they just stopped laying about 4 days ago. i feed them a mixture of scratch and chick starter. oh, and i also found a quail egg that is bigger than the other. I think it might be a double yolked, am i wrong or right??????? what could i feed them to make them start laying again??? or is it the red light??? Could someone please tell me what the problems is because i wanted to incubate some of them.
