Morgan, if you are using a deli container or plastic type sandwich container for eggs, you should be using dampened vermiculite, damp as in not wringing wet or dripping but kind of clumps if you were to try and mold it together.
The the eggs are put in, DON'T let the eggs roll. You do not want them moving around now 
If they get a yellowish/browinish they are too damp, let container dry out a while.
If they begin to cave a bit, add some water, (NOT to the eggs themselves) this makes them get moldy. Just add some around the sides of container, away from the eggs.
The sand will not harm them, yours looks more like pepples,
but may fall off itself. Don't try handling eggs to get it off. Leave them alone now.
Best wishes Pal !
