Ok here is a hypothetical scenario: I have 10 female white-leghorns and 1 male leghorn to make the eggs fertile. I have an incubator which holds 270 eggs. I want to save up enough eggs to fill the whole incubator. 1) How long do fertile eggs last for after they are laid? 2) What do I store fertile eggs in so that they remain fertile for a while? I do not want to start the incubator until I fill up all 270 spots. Is this possible?
