Yang Mo (68), who lives in Haejang-dong, Jeju City, has found an unusually large egg while collecting eggs from chickens raised at home.

At first, Yang looked at a poisonous large egg and thought it would be trivial to have a double egg.

However, considering that the blue egg is relatively small compared to the general egg, there was an unusual point.

When Mr. Yang went home and broke the egg right away, there were two yolks and a small egg, not two yolks.

Yang said, "There were many cases where two yolks were found in one egg, but I saw eggs in the egg for the first time in several years while raising chickens."

Another egg in the egg was quail egg-sized, perfect for the skin as well as the yolk and white.

So why did this happen? According to the Livestock Quality Assurance Institute, eggs in the form of small eggs in eggs are also called 'poor eggs' or 'double eggs' and are classified as malformed eggs.

The Livestock Quality Assurance Agency explained that the occurrence of eggs in the form of eggs in the eggs has occurred in the past but is not common.

This double egg is believed to be a phenomenon that occurs when the chicken makes eggs, but it cannot be discharged outside the body, making eggs again.

An official from the Korea Livestock Quality Assurance Agency said, "Eggs in eggs can be considered as mutations in a strict sense."
