Zamboy,
a queen lays 1 to 2,000 eggs a day so she is on a continuous laying pattern (every minute or so on average). There is no specific 'time she lays'. But as she does not like light, when her frame is pulled out she could stop and oftentimes she'll wander around on the frame surface. That could be why you may not see her laying.
As many here have recommended, if unsure about eggs, check for young larvae, you'll know things are good, and avoid frequent disturbance.
Good luck in your new endeavor.
