I would get someone lined up to watch, that could get the eggs in the bator for you, or see if there is a breeder nearby that would take her in while your gone. (They would know exactly what to do).
There is a thread posted just this morning from someone who found her girl on eggs after being gone 5 days and one looks like it may be a lost cause. And while the others look fine currently, who knows how consistant the temps have been while the mother was on them. Just my 0.02 since you asked.
