Ok thanks!this is only my opinion based on what I read here. Unwashed eggs will keep for a couple of weeks on the counter. I've personally eaten eggs that have been at room temp for 2 weeks, and they were fine. If you wash them, you need to refrigerate since you wash off the bloom that protects them from bacteria. You shouldn't ever wash eggs you are going to hatch, either, for the same reason. I have read that they will hatch after sitting out for 2 weeks, but that the viability goes down after 1 week. If she shows signs of going broody, you should be able to let her lay her own clutch, but my BO stopped laying 3 days into her broodiness. She has been on the eggs for 6 days so I'm hopeful she will stay faithful to them. I'd go over to the incubating and hatching thread and look at the sticky about care of hatching eggs. It is really interesting.
