Chicken lays very weird giant egg

Over-egged chicken lays monster two-yolker.

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.

Poor chicken.

    We had chickens, and have seen both double yolks, and egg in an egg, but not together. i agree, those eggs are HUGE – poor chicken!

    When the missus was pregnant with our first her OBGYN said the ultrasound showed twins. That afternoon I started making supper and I cracked an egg and it had two yolks! But we didn’t have twins. The egg omen lied to me.

    Am I missing something “Double shelled eggs are so rare that no one knows exactly why or how they happen.” is the why – “an egg that is nearly ready to be laid reverses direction” and the how – “gets a new layer of albumen covered by a second shell” or is it just too early in the morning for me to understand properly. Also maybe not that uncommon as one of my brothers chickens did the same and when I started keeping chickens was told it could happen. Great Blog by the way.

    On the one hand, I am incredibly sick of the “-ception” meme.

    On the other hand, I can’t pass up saying “eggception.”

      I really wish I’d thought of that.
