[Chondrodactylus]

My female rugosus laid two eggs, buried about 2-3cm under the substrate the one looks like it had been stood on so subsequently was cracked and contained a white gue so im sure it's infertile. But the other egg looks okay no cracks ect.
Does any one have experience breeding and incubating eggs?
And will she like other geckos drop more in the follow weeks or will they be her two for the season?

Thanks
