The family in the video was understandably freaked out by the giant egg and the surprise egg inside, so they ended up using them to make a hair conditioner instead of eating them, according to the video's description. Both of the eggs should have been fine, though, according to the report, and probably would have made for a damn good omelette.
While it's unlikely you'll ever find such an egg-ceptional (OK, we'll show ourselves out now) egg in a carton from the grocery store, just imagine cracking one open to find another egg inside. The man who uploaded the video, for one, is still in shock judging by this line from the description: "I can't believe it didn't kill my hen." But, really, that's crazy.
