There for a while when our Australorps first started laying, we got a lot of double yolkers, one day Sally laid this monster egg that would'nt even come close to fitting in the slot in a large egg carton. Then she did'nt lay for about a month! I'm surprised it did'nt kill her! There was a guy on cnn a while back that had a hen lay a huge monster egg and his hen died later on that night!
