My society finch eggs laid eggs and are bathing a lot more often?

my society finch laid eggs { i do have a male and i am uming that the eggs are fertilized} so anyway it is getting closer to the date the eggs should hatch because today is the12 day and i am noticing that the parents are bathing a lot more does this mean the eggs are due to hatch very soon?. { could it be because they are trying to make more humidity for the eggs to hatch}?.
