Thanks. She has been with a male. Should I keep them together? I have them separate at the time being. What is the best way for me to heat the eggs without an incubator? Sorry very new at this.If you have the incubator at an appropriate temperature with a decent thermostat, and you have the eggs in a container with moist substrate and a secure lid with no holes in it, you've probably done just about everything you can do. If this is the female's first clutch, they may not be fertile but she may lay every 2 weeks. If she hasn't been with a male (which I don't think is the case since you got an incubator), then obviously the eggs won't be fertile. I've experienced everything with leopard geckos from females who laid 100% fertile eggs, to females who laid a few dud clutches before getting it together to females who were unsuccessful at producing fertile eggs even after several years of trying.
