how long do eggs last before they need to be brooded?

[watersoflethe]

i'm trying to collect as many eggs as possible to brood all at once..
i was wondering will they go bad as i'm waiting for more eggs to come?
how long do they last?

General rule of thumb is 10 days, but it can vary.

How many eggs can the broody hen cover is a bigger consideration. Or are you incubating eggs?
