I currently have a flock of hens with no rooster. I do not wash my eggs nor store them in the refrigerator, like most European countries. Eggs are usually eaten within a few weeks to a month & I have never had an issue with spoilage. I eventually plan on having several flocks with associated roosters so that I can have pullets for meat. if I decide for Eggs to not incubate and they are fertilized if they are kept on the counter is this an issue or do they HAVE to be Refrigerated?
