As I opened the door to the nesting boxes this morning, I grabbed 2 eggs, then looked into a box and my Speckled Sussex Shirley was sitting on another chicken. The other chicken's head was poking out from under Shirley. I lifted Shirley up and there it was. She must of, had to have been, startled by the size of this egg as it made it's entrance or "exit" into the nesting box. Her "normal" egg in the first one in the top row, that was from yesterday.
