A Tasmanian woman has been left shocked after cracking open nine double-yolked eggs – a ‘one in one octillion’ occurrence.
Elise Cleary said she made the extraordinary find in Valley Brook Free Range Tasmanian eggs that she bought from the supermarket.
After cracking three double-yolked eggs for breakfast on Friday and again yesterday morning, Cleary decided to test her luck by buying another, brand new half-dozen carton for dinner – along with a Lotto ticket.
“I’m trying to make a hollandaise for dinner… and I figured I’d record it just in case,” she said while successfully cracking her sixth double-yolked egg.

“I’m gonna do this again, I don’t even need this many eggs, I’m just gonna do it again.”
She then went on to crack her seventh, eighth and ninth double-yolked eggs in a row.

“What the f**k… what’s going on… oh my god, oh my god, oh my god,” she said after finishing with 18 yolks.
According to ‘Dr. Karl’ Kruszelnicki, the chances of getting a double-yolker are about one in 1000.
Theoretically, this means the likelihood of getting nine double-yolk eggs in one carton is about one in one octillion chance (or 1 in 1,000,000,000,000,000,000,000,000,000).
Dr. Karl says double-yolkers occur when a hen’s “ovary is too enthusiastic” and releases more than one yolk during her daily ovulation cycle.
Although double-yolkers can look off-putting to some, they are safe to eat.
