I would agree with the above. Take the eggs out, or replace them with dummy eggs, or shake them about to 'scramble' them. What happens if the parents are harming the babies/arent' feeding them properly/aren't laying on them to keep them warm and suddenly you have a clutch of babies that need your care to stay alive 24/7? You work full-time. I wouldn't let them keep the eggs.
I did have a mated pair of cockatiels have babies last year while I worked full time and when one baby became picked on by the others, mom and dad would pull its feathers out and it stopped getting fed. I had to pull and hand-feed the baby, and luckily it took to formula great and weaned just fine, but without my help and knowledge of how to feed it, it would have absolutely died.
Please don't let your birds have babies unless you have experience hand-feeding, a brooder, and proper knowledge of how to take care of unweaned baby birds.
