Don't worry. If the eggs are in the lay box, then the humidity is fine, and that is one of the big worries about eggs out of the proper container. As long as humidity is high in the lay box they could last for days, if not week or even the whole incubation period in there.
The only other worry is tempature. As long as the temp is above 75 or even 70 (but this is cutting it close in my opinion) and below 85 then the eggs will do fine. Any where above 86 or so is VERY bad, although the eggs can survive a few degrees above that there is no point in risking it.
As long as the eggs are in those conditions they should do fine. Concgrats on the eggs!!
