How long till eggs will not be fertile

[kscottjoyce]

Hey there,
I recently gave my rooster a new home at my sisters coop. Just wondering how long it takes before eggs will no longer be fertile with my hens now that the rooster is gone.
thank you for your help!

Eggs are fertile for an average of usually around 10-14 eggs after mating...

I've heard up to 4 weeks

I have heard a lot of different numbers... I just kind of form an average of what everyone says... 10-14 eggs would be around 2-2.5 weeks. Depending on the hen...So I have no idea. I know its longer than a week and no longer than a month. Lol.
