The sand may dry he eggs out..it's hygroscopic...get some coarse grained vermiculite (gardening centres have it) and use that instead. Make it just moist enough that when you take a fist full of it you can't squeeze any more than a drop or two of water out of it. pit a layer of it in the bottom of a container and gently move the eggs to the new container without rotating them. You may want to use a spoon so you don't damage the eggs. Lay them in rows about 1" apart in all directions. Put the
I'd on the container and set them somewhere that the temperature is about 74F.. Make sure it's in a dark area.
You can also use hatch rite or other substrates recommended by people on here if you want to...I'm just telling you one method.
