Katie Denne wasn't quite sure what was going on with the giant egg she found in her hen house until she cracked it open.

The good news is the hen survived.

The better news is that the mystery surrounding the monster egg Katie Denne found in her Campbell River henhouse Tuesday morning has been solved.

Turns out it was actually two eggs in one  — a fully formed egg containing another fully formed egg.

"It was the size of my hand. It was ridiculous," said Denne, noting that she had to be careful handling the giant egg because the outermost shell was "oddly super fragile."

She admits she wasn't quite sure what she had at first.

"Double yolk eggs are common and we've had a triple yolker once. But this looked like it was from a dinosaur," she said.

It was only by cooking the egg — with husband Kyle taking video — that the case was finally cracked. 

"We were thinking there would be four yolks in it or something crazy," she said. "We cracked the big egg and the yolk came out — a smushy yolk — with the white. And then a whole new egg came out!"

Earlier this month a hobby farmer in Ontario also discovered a rare egg-in-egg.

He had his egg X-rayed.

Denne's family has kept chickens at their Holly Hills farm for years collecting five dozen eggs a day from 60 hens. This is the first time they've come across an egg-in-egg.

According to Denne's six-year-old daughter, Cora, the egg-in-egg was "really yummy."
