An egg will typically last about 3 weeks when stored at room temperature versus about 4 months when kept in the refrigerator.
How long do unwashed duck eggs last?

If the temperature drops for any reason, the hatch will take longer. I’ve had chicks hatch as late as 26 days after setting. For that reason, I advise not to discard any (as long as candling has shown development) before that. A Wyandotte chick at the point of hatch – a little ‘late’ but perfectly healthy at day 23.
