Small Eggs

Small eggs vanished from the market because they are sold in disguise encased in the boxes marked Medium; and, so, Medium is Large, Large is Extra Large, and Extra Large as JUMBO. Or, have hens, hormon-fattened, stopped laying small eggs? In fact, medium eggs have more recently disappeared, too. The thought occurred to me because the dozen eggs I got at the neighborhood Green Market recently were visibly and demonstrably small, very small.
