I am wondering if this is a true observation, if any one else has noticed it to be true or not? My coturnix quail that are not supplemented with extra light have stopped crowing. Would you assume then the eggs are not fertile? or at the least, not really good fertility rates? They are not laying very many eggs either. I have another pen that are supplemented with light and the males DO crow still! And still get eggs from them. So would you assume these ARE fertile? So my observation being: Crowing = fertile and egg laying no crowing = poor fertility and lack of egg laying What do you think?
