Question

why are the sizes of eggs different?​

Answer 1

Explanation:

Egg size is related to the age of the hen -- as a hen gets older, she lays larger eggs. Eggs are sorted at the grading station based on weight, not circumference, and packaged accordingly into the following sizes: pee wee, small, medium, large, extra large or jumbo.
