Picture of How to breed Leopard Geckos
To breed leopard geckos you will need a few things to be successful

-First of course will be at least 1 male Leopard gecko and 1-4 female leopard geckos

-You will also need a 10 gallon tank to keep the male in

-Also a 20-30 gallon tank to keep the females in

-A heat mat to heat the cages

-For the female cage you will need a laying box. A plastic sterilite shoebox will work well with a hole cut in the top filled with damp peat moss.

Step 1: Getting the geckos to the proper size to breed

Leopard geckos should be around 50-75 grams to be able to breed. Some will be much larger, but this is the recommended minimum.

Step 2: Introducing the male

To introduce the male you need to be cautious of a few things. Normally introducing a male into an established female tank doesn't cause any problems but  you need to be concerned with aggression either way. A little biting is OK and should not be worried about but if you start to realize injred geckos separate them to avoid further problems.

Step 3: Checking for eggs

Periodically check the box after a few weeks for eggs. You need to make sure to get to the eggs quickly because they can eventually dry out.

Step 4: Removing the eggs

When removing the eggs you want to try to make sure to not turn the eggs over because depending on how long they've been there you could potentially kill them. Move them to a proper incubation container, deli cups work well. Fill the cups with moist vermiculite. You want the vermiculite to be moist but not too wet.

Tip: It helps to draw a mark on the eggs while they are still in the lay box so you know which side is up.

Cool this is #1 on google
I would strongly recommend AGAINST using vermiculite due to its likely contamination with deadly asbestos fibers.  My partner of 24 years now has mesotheleoma caused to his exposure to vermiculite over 40 years ago.  It is a deadly cancer that has no cure - there is only palliative care. He was diagnosed 11 months ago - typical life expectancy is 9 to about 15 months after diagnosis.  So please use anything else but vermiculite. It is deadly stuff.  Thank you. 

There is no asbestos in vermiculite. Vermiculite itself does not contain asbestos; it was just the Libby, Montana mine which was contaminated because of the presence in the mountain of a secondary mineral called diopside. (To read more about diopside, go to sites like The Mineral Diopside.) This my have been a "contamination" issue 40 years ago but it is not a threat now.

Could you add a bit more to determining the sex of the geckos by what temperature you incubate at?
