How long can you keep collecting fertile eggs before incubator

[Michele]

How long can you keep collecting fertile eggs before putting them in the incubator? Is it only six days or two weeks? I have blue cochins and blue giants and I don't want to lose any if possible!!
thanks for you information!

General rule of thumb is to set them no later than 7 days after they are laid. However on occasion that rule has been pushed out for 10 days or longer and still hatched. But for best hatch rate, you want to do it within 7.
