panther gecko eggs

[Psychedelic]

OK, so a few days ago I went to the pet store and bought a brand new trio of panther geckos which I expected would begin laying eggs at some point. Well the day after buying them I found 2 eggs already. I don't have an incubator as I was not expecting eggs that quickly and just spent way too much money at the pet store to begin with. So I put the eggs in a small plastic cup with some moist paper towel and put it over the heating pad. Anyone have any better suggestions as to what to do with the eggs. They are nice and white and appear healthy.
