I'm gonna assume that this odd egg was found in a Chinese supermarket, if only because the image came from Xinhua. Regardless of the egg's provenance, it's pretty bizarre. As you can clearly see, this is no mere double- or triple-yolked egg, but something much rarer, an egg within an egg. According to Poultryhelp, such freaks of nature appear when an egg that is nearly ready to be laid reverses direction and gets a new layer of albumen covered by a second shell.
The supermarket found the concentric egg when it was sorting broken eggs out of a delivery from a farm. The inner egg had a soft shell and was half the size of a normal egg. Alas, there is no word on what the egg fried up like.
