Hens lay one egg at a time, of course.
What about two-yolkers?
Sometimes they can lay two at the same time, one complete egg with a shell inside another with a shell, when their timing is off and the muscles don’t contract in an orderly manner. It isn’t as common as a double yolk in one shell, but but it can happen.
WAIT UNTIL CITY SLICKERS FIND OUT THAT A CHICKEN HAS ONLY 1 OROFICE THAT DROPS OUT EVERYTHING===EGGS INCLUDED !!!!!!
