How long can eggs set in coop unattended and still be hatched?

Definitely invest in a candler. I like mine very much. There is a rechargeable version too that won't break the bank ($14-16) if you want to candle them right in the coop and don't have an outlet. It's perfect for "uh oh is that egg developing" and of course actual intentional brooding/incubator work.

Is there a deference?

Duck eggs seem to have a longer shelf life than chicken eggs. It hasn't been unusual for my ducks to lay well over 14 eggs before going broody; with all or most of the eggs hatching. With an egg a day and days when an egg isn't laid, that makes the first eggs well over two weeks old before incubation started and they still hatched.

I have an egg candler. My bright flashlight works better and is more convenient to use.

Thank you for the reply!

The flashlight on a cell phone makes a good candeler.
