One of my easter eggers laid an egg that is (not eggagerating) twice the size of the others. They've all been pretty standerd in size. this one is so large I can't close the egg carton with it inside. Never seen a chicken egg this large. It is Duck sized, if not bigger! What is going on? Clues: (that may or not be helpful) it was laid on the coop floor just under the nest box, it was covered with poop and some blood smears, the cone end is rough and patchy. I can't post pics.
