It cant. The egg slowly absorbs water, once it absorbs enough their is to much water and basically you can say the embryo drowned but the egg can absorb a good amount of water and still make it.
You need to cover the egg completely and put a 75watt bulb over the egg and keep the egg moist like your doing. The sand needs to maintain a temperature of around 84 degrees F
If you can i would run out and try and get a simple chicken incubator. Its much better then trying to hatch it with a light.
To tell if an egg is good your gonna have to gently uncover top of the egg in about a month to see if the egg is "chalking." This is where the calcium from the egg shell all moves to the middle of the egg and forms a band. You could also try candling it haha but thats envolves picking it up and trying to be very careful. i dont recomend that.
If you dont see this band in a month the egg is most likely bad.
