You could collect the eggs for a few days ... even stored on your counter out of the sun, then when you have enough put them in the incubator ... usually best fertility rates will be from 5 days or less old eggs ... of course if you have a broody hen, you could also collect until you have enough, then put them all under her, so they will hatch about the same time ... mark the ones you put under her with a pencil, and remove any new eggs (no mark on them)
