I routinely collect eggs for up to 21 days before incubating them. While the claim is that hatchability decreases with the length of time the eggs are stored, eggs don't suddenly become non-viable after 10 days. Their viability may decrease slightly with time but more of it has to do with how they are stored.You can do it however you want, but since you asked, I’m just letting you know. Thirteen days after lay is likely not going to work.
Three times daily is recommended.How often should I turn them
