double egg

I love this homemade video, and how it shows just how crazy the world can be.

One of Sean Wilson's chicken laid a huge egg and when he cracked it open, it contained another egg. Not even a hoax! As the curator of the egg collection at London's Natural History Museum explains, the double egg is rare but real and results from a fully formed egg being pushed back into the ovary, where another egg forms around it. Here's another double egg and a report of a Texan double egg.
