Leopard gecko breeding questions

[Lizrd_boy]

Soooo, Lea is large enough for breeding, and she was ovulating, so I put her in with my friend's leopard gecko, Scales, who is a male. They mated and Lea tried to stay away from the male, so I took her out and put her back in her own tank. a month and a half later, the ovulations are being reabsorbed back into her body

BUT.... Lenetta was ovulating, and on the 1st of March I put her in with the male. They mated, Lenetta rejected the male and got him off of her, and walked away. at that point I took her out and put her in her own tank. Now, (I think it's the 11th??? I forget ) I can see through her belly that the ovulations are now about 2.5 times longer and white. I'm thinking eggs!!!

I have a hova-bator incubator (I removed the egg turning mechanism) that I have calibrated to 89* F (I'm trying for males since I will be keeping one and the person getting the other one doesn't care which sex she gets, and there is still a small (about 2%) chance that one of the eggs will be a female and I don't want to accidentally get both females). I bought 12oz plastic deli cups from Walmart and horticultural vermiculite from Value (It doesn't have any fertilizers or other additives). I have enough vermiculite to experiment with to make sure I can get the right medium:water ratio. I mixed equal parts of vermiculite and water by weight, and got a mixture that (after being thoroughly shaken) feels damp, and sticks somewhat to my hand, and when I squeeze it no water comes out. When I cup some in my hand, tilt my hand, and shake it so it slowly falls off, it does not clump together, but when I squeeze it it clumps well.

I still have a few questions, though.

1). I will be checking the eggs every day or every other day. I was planning on putting 1 pinhole in each incubation box (I want to incubate the eggs seperately so that if one gets fungus or mold it won't damage the other one). Is that enough?

2). If one of the eggs develops mild mold or fungus, should I moisten a qtip and wipe off the mold every day?

3). what are the odds the eggs are infertile? Lenetta has never mated before, and has never layed eggs.

4). The horticultural vermiculite I'm using has no additives or anything, but is it possible that it it contaminated with something that will harm the eggs?

Also, any tips are helpful. Although incubation temps are different from species to species, a lot of tips from other lizard species would probably be helpful.

Thanks!
