I always take the eggs from the females within 48 hours after them being laid. From what I remember though, all the taeniura subspecies I've bred have stayed with the eggs until their taken. They rarely give them up without a fight either.

Their was a article I read years ago on taeniura callicyanous(blue beauties), if I remember correctly, where the person left the eggs with the female. She stayed with the eggs until they hatched. I don't remember if it was a second clutch with the same female or another female he had but it seems she left the eggs some time during incubation and the clutch had to be taken to finish their incubation.
