Hi all, While letting the hens free-range yesterday, I was walking around and checking things out. I stumbled upon an egg from one of my girls, but not sure which one. I don't know how many days it's been out there, but the shell was in good shape. When I thump on the egg, it sounds like it's lighter when compared to others I already have in the fridge. And, it sounds like I'm thumping a glass shell, as it has a distinct "ring" to it, unlike the others. I also weighed it to compare the refrigerated eggs and it was about the same. How long can an egg be left outside, unrefrigerated, and still be safe to eat?
