I have a clutch of Veiled eggs that I have had since the end of September. She had contact with a male once or twice just previously to showing signs of being gravid. It was such a short time afterwards that she laid her eggs, that I thought she might have been gravid before she was placed in with the male. I never saw them breed, but thats not to say they didn't. Just to be on the safe side, I've kept them. How long will an infertile egg last before it shows signs infertility? These look super great. They are like the size of jelly beans now, and it's been like 3 1/2 months now.
