I weigh all of my eggs. If an egg weighs less than 42 grams it is considered a pee wee egg. I weigh all of my eggs in grams.
Exceptionally small eggs are called "wind eggs" or "fart eggs". They are usually darker. Very small eggs with regular coloration are called a "Pee Wee" egg, which is an egg that is less than 42 grams. Probably most people that do weigh their eggs do it in ozs. I personally use grams.
