Easter came early for a chicken-raising family this year. Instead of a chocolate candy inside an egg, they got a Russian nesting doll-style surprise.
YouTube user SNO Multimedia posted a fascinating video over the weekend showing a giant mutant chicken egg. The lumpy-looking creation dwarfs a normal egg. When cracked open, the egg reveals a yolk and another fully formed egg inside. That smaller egg also contains a regular yolk and white.
Though the egg-inside-of-an-egg phenomenon is rare, it does happen. It's due to a counter-peristalsis contraction, which happens when an egg is pushed back up into the chicken's reproductive system and becomes embedded in another newly forming egg. It's exactly as strange as it sounds.
SNO Multimedia's video description is an instant classic: "This gigantic egg had a yolk and another egg inside. I can't believe it didn't kill my hen. No one wanted to eat it, so my wife made a hair conditioner with it." At least the hen's monumental effort didn't go to waste.
