I've had a pair of ringneck doves for a few years now. Every month they mate many times a day, the female lays 2 eggs, they sit on the eggs, and the eggs rot. Candling always shows empty eggs. I was told the other dove was a male, but he cant seem to fertilize any eggs. I've read that female/female pairs will lay 4 eggs since each female lays 2, so it doesn't sound like I have two females. The male bows and coos and does everything a male is supposed to, except fertilize the female's eggs. As it turns out, the male is a result of many generations of inbreeding. I'm not sure if that could effect his ability to fertilize eggs. Maybe its the female who's having the problem? I'm so confused! But I'm 100% sure I know which one is the female. I've witnessed her lay eggs many many times. The female is the orange pearled, and the supposed male is the rosy.
