Okay, I've just about seen it all. Eggs laid with just barely a membrane, eggs with soft shells, deformed eggs, double yolks...but never this. One of my Jerseys has laid the tiniest egg I've ever seen. They normally lay good-sized large eggs, but this one is bantam sized and perfectly shaped. I candled it out of curiosity, and it has no yolk with only a tiny air cell about the diameter of a pencil eraser. I laughed my butt off!
