If you intend to keep crested geckos, you may wonder whether or not you should try to breed them. If your crested gecko cage is large enough to hold 2 or more geckos breeding becomes an option. If you do intend to get male (just one please!) and female crested geckos, you will be quite likely to eventually find some eggs in your cage, if you provide the right climate, food, space etc.
Personally, I find that breeding reptiles is the ultimate reward when keeping them. There is nothing like finding a baby gecko in the incubator.
There are a number of factors to consider though, before you decide to breed them. For one, you will need an incubator for the eggs. You can choose to buy one in a shop (see the one that I have in my Amazon store), but you can also build one yourself.
If you decide to go down the DIY route, you will need a heat source, such as a heat mat or cable and a thermostat (again – check out the one on Amazon). I have used a plastic aquarium with a heat cable inserted. I fill the bottom part of the aquarium with about an inch of water and immerse the cable in the water. I then put a little stand into the water (like a little box or so) and onto that I place a (cleaned) cricket box. The cricket box is filled with vermiculte, which I keep moist (not wet!). This is where the eggs are placed. Right next to the eggs I place the sensor of my thermostat. Finally, I cover the aquarium with a lid (cling film will also do), leaving a little space to allow for some ventilation. Do will have to cover the cricket box with a lid with holes when you get closer to the hatching date to avoid your baby geckos falling into the water of the aquarium!
Set your thermostat to keep the temperature between 78 and 84 degrees F (26-29 degrees C). You can expect your geckos to hatch after 50-70 days.
The DIY route is certainly cheaper (although you will need the heat device and thermostat), but since you can expect a female to lay 15-22 eggs per year, you may actually decide that buying a manufactured incubator is worthwhile. It is cleaner and safer.
If you have any other DIY ideas, I would be keen to learn about them – just respond to this post!
Good luck with breeding!
