Hi, today I found an egg in the kiddy pool that my ducks use for swimming. I'm pretty sure it's fertile, as she has been getting lots of "attention" from the drake. Does the fact that it was under water (for up to 2 days) make it un-hatchable? I have a hen who has gone broody and would like to use her as my incubator. These are my first ducks, so I'm just not sure.
