How to hatch the egg of tokay gecko without incubator?

Once tokay lay their eggs like many geckos they are stuck to the surface wherever they were laid. If it chose to lay them in a certain area it may very well have picked the perfect spot. Oh and to the other guy that answered, you do NOT place them in soil and cover them up....snakes or geckos.....snakes like temps around 88-90...geckos....84-88. Your best bet is to leave them where you found them and just countdown the days.
