I have 4 female coturnix that stopped laying for the winter, which I hear is normal. I have tried a few things in attempts to get them going again. I just recently found a better food source on amazon that has 22% protein. I also add mealworms and oyster shell to the food mix every once in a while. I think my problem is proper lighting. I tried to use some solar powered light, but I don't think its powerful enough. Has anyone have any other good secrets for getting females to lay again. Do I buy a male...even if I don't care about fertility? I've heard setting up white xmas lights around the inside of their cage can act as the additional lighting for the shorter winter days.
