A short time at 90 F won't usually kill them but it's possible, esp. if it got even a bit hotter than that. Dead eggs will stop developing and eventually become slimy/moldy.
One issue is that the dirt around them dried up because of how much water they absorbed. One looks a little shriveled up! The others are solid but what should I do to moisten it up again?
You have to add water to it ASAP but not get the eggs wet. Drip water with an eyedropper or pipette all around the eggs, it may take a while but it has to be done. If you are VERY careful you can use a spray bottle with a direct stream but keep a paper towel in hand to dab up any drops that fall on the eggs.
Sorry for the late reply but 1 has hatched! There's another one that has it's head sticking out and it's been like that since yesterday night. The rest of the eggs are collapsing! Yay!
