HELP!!! First Egg!!!

[spikeswithskills]

so i looked at my female beardies cage and i saw an egg sitting on top of the sand!!! i searched the entire cage and there were not any other eggs. but the egg didnt look completely white and had tan areas on portions of it. Is this normal? also, will the other eggs be arriving shortly? i had been dusting the crickets with calcium and vitamins..... is she calcium deficient? i installed a reptisun 10.0 just now because i saw the egg... also her belly does not seem completely expanded, so i didnt think the eggs were completely developed..
please help!!
thanks

Did she lay any more eggs?

Has she been digging or scratching, or just acting normal now?
