If I were you I would change the soil to vermiculite. They seem to incubated real well in it and its easy to keep it moist etc. Others use perlite and dont have a problem. Are the eggs in a incubator? I use a thermal hovabator, only around 38 bucks and it works great. You have to buy a digital thermometer for it though because the one it comes with is highly inaccurate.
Keep the incubator at around 82-84 degrees. The babies should hatch anywhere from 60-75 days. Sometimes a little sooner, sometimes a littler later.
Be prepared to have many aquariums or bins (rubbermaid) to house the little guys. You dont want to put too many to a cage or you will have some major mutilation problems. I try not to put more then 3-4 hatchlings to a ten gallon aquarium. Occasionally I was forced to put 5-6. But only for a week or so. As they grow you need to seperate them by size and make sure you dont have many to a cage.
The biggest thing with the babies is they eat ALOT! One baby beardy will eat anywhere from 30-60 crickets a day. Some eat 70-80. Make sure the crickets are no bigger then 1/2 the length between the eyes. I usually order 1/4 inch crickets as soon as the first one hatches. It can take them a couple days to get a appetite. Order alot of them!
Of course your going to want to heat and light the cages. Keep the basking spot around 105-110 and the cool side around 80. Dont forget the uvb/uva flourescent bulbs 
Dont forget to supplement their crickets with calcium daily and herptivite approx 2 times a week. Offer them finely chopped greens and veggies daily (removing them at night).
For water you can spray them daily, give them baths a few times a week and/or use a small syringe and drop little drops of liquids on their nose and they will drink it. Some put a SHALLOW water disn in their cage. But in general baby beardies are not very good when it comes to drinking water out of bowls. They just dont get it!
For a substrate I would highly recommend non printed, white paper towels. Easy to clean and you dont have to worry about them eating sand etc when they eat their crickets.
This is not a detailed caresheet, just some basics. You might want to read some caresheets, read some posts and learn as much as you can, before the babies arrive. Congrats and goodluck. LindsayMarie
