That's good, hopefully she'll lay her eggs soon then. I see her pics and although she's a wee bit slender in the tail is not at all underweight. If you see the " hip" bones beginning to show, then she needs to eat a bit more in between laying. A breding female that is getting thin should never be housed with the male. The male should go in to a different tank and the female should be allowed to eat twice a day and have calcium on every other meal. They usually don't eat in the days before laying but whenever mine take more than 3-4 days to dig and decide to lay I offer them something just in case they're hungry. Once in a while they will eat but usually not.
The eggs do look good. I've never seen them incubated like that, I think it risks them getting dehydrated if they're not partially buried in something. Where did you see that type of incubation ? Do you know the temp. they are at with that blazing light on them ? You're actually better off to have them too cool than too hot. They can survive + hatch at 75 degrees but will die at 95....but you want to shoot for 82-86. Here's how I do mine in a shoebox with 3" of damp vermiculite. Nearly 100% hatch rate over years of raising them. https://www.beardeddragon.org/media/29884/full
I got it from the pet shop that I got my lizards from. you put water in the bottom then place it under the heat lamps. I hadn't seen them before either but apparently it works really well. I figured it would be easier to setup.
