Fairy Eggs

We got our first "Fairy Egg" and while I had read about them before, when researching egg production, I still was shocked to see one. I couldn't believe this tiny little egg came out of my chicken! The size difference is crazy! 

For those of you that don't know what I am talking about:
Sometimes your hen will lay a small, yolk less egg. This happens because a tiny bit of tissue or even a foreign mass enters the hen's oviduct and their reproductive system sees it as a yolk. The egg forms around the tissue as if it was yolk, creating a smaller yolk less egg.

Other names for it: Cock egg, fart egg, wind egg, witch egg, oops egg, dwarf egg
Perhaps the name "Cock egg" has been around the longest. Because they egg has no yolk, they believed that cocks laid the eggs with no viable genetic materiel. Obviously, cocks do not lay these odd bolls. They are just a fluke in nature.

Superstition: Some people believed cock eggs, because they come from cocks, are magical and a bad omen if brought into the home. They were seen as evil and "of the devil". It was said that witches valued them as a rare ingredient in potions. In order to save your home from illness, you are to throw the egg over the house to break on the other side.

I didn't throw mine over the house! I think it is a cute little thing!

Please share your photos and stories! What is your name for these odd little eggs?
