A chicken in China is being hailed as a miracle after it laid a monster egg containing two yolks and another egg inside it.
Locals were amazed to find the egg, which was three times the size of a normal egg, weighed in at over 200 grams.
The chicken had reportedly shunned the corn the rest of the hens were eating, so was being fed a different rice diet.
It’s unknown whether this has caused the over-development of the eggs.

Double-yolk eggs are rather common. There are even cases of triple yolk eggs.[source]
Double eggs are explained thusly:
An egg within an egg, or a double shelled egg appears when an egg that is nearly ready to be laid reverses direction and gets a new layer of albumen covered by a second shell. Sometimes the reversed egg joins up with the next egg and the two are encased together within a new shell. Double shelled eggs are so rare that no one knows exactly why or how they happen.
