If you can see the eggs and she is digging frantically, she is probably ready or just about. You NEED to give her a place to lay her eggs. Buy some potting soil or another substrate that can hold moisture and shape. Make a lay in a plastic tote bin. Make sure it is at least 12" deep. You can even try starting a hole for her. Make sure there is a heat source on her too. Let her spend the day in there. Sometimes, they are really finicky about where they lay, I have had to make special places for them to lay inside their tank because they refused the bins.
Once she lays them, you have to decide what you want to do with the eggs. If you don't want a whole bunch of babies, put them in the feeezer. It sounds cruel but baby dragons are A LOT of work. They need to be fed 2-3X a day and can easily eat 50-70 crickets a day EACH. You also have to keep them
hydrated by misting a couple times a day. The will nip off the tails and toes of the tank mates sometimes, so you have to be ready to separate the larger babies or more dominate babies.
Also, bearded's can retain sperm and lay 3-4 clutches from a mating...
If you DO decide to keep the babies... The eggs cannot be turned. They have to stay in the position they were laid. If this is her first clutch, then they may not be fertile and some might just fail to thrive. They need an incubator high humidity. You can use potting soil( I sterilize it in the microwave) or vermiculite if you can find it in a plastic tupperware container. Get the substrate moist, make indents in it, place the eggs in it with out turning them. Put a lid on the tupperware with small holes for ventilation, then place them in the incubator. You can usually tell by a week or two which ones are good or not good.
I definitely think you should read up online as much as you can about all of it. It will help a lot knowing what to do. There is a lot of info out there.
