we collect our eggs daily, around 6 pm. if they are for eating they go straight into the fridge, if dirty, damp cloth then dry. if we are selling them, we clean them with a damp cloth and dry them. if they are gonna be for hatching, we collect them for about 7-10 days, leave them on the counter. why we do it, because this is pretty much what all of the info from this website recommends to do. so far so good.
i did learn on here that if you find some eggs in your coop and don't know how long they have been there, you can put them in a container of water, if they stay on the bottom, they are still good to eat, if they float they are bad.
