Coles customer's insane discovery inside eggs

A Coles customer has taken to Facebook after a very shocking find in his eggs this week.

The Gold Coast man was stunned to find every single one of his Coles Jumbo Free Range Eggs were "double yolkers", sharing the find to the Coles Facebook page.

"Carton full of double [yolks]!" he wrote excitedly, adding the hashtag, "#mutantchicken".

In one video, a young boy is heard saying: "We [found] a mutant chicken, there's like, one, two, three, four, five, six – we've only cracked open six eggs but there's 12 yolks!"

His dad gets ready to crack another egg with the boy saying: "It's going to be a double-yolk! I swear on my parents' lives... Look, double-yolk!" as another egg is cracked revealing the seventh double yolk.

"What is this?" the stunned boy questions.

According to the ABC, the chances of getting a double-yolk in your carton is one in 1,000, but the chances of getting four in a row is higher than you might think.

Double-yolks are likely to come from young chickens whose ovaries are too "enthusiastic" and create two yolks.

You're also more likely to find a double-yolk in a large or jumbo-sized egg.

The reason you could have a whole carton of eggs that are double-yolkers could be due to the fact the chickens are all likely to be the same age and if they're young, they're more likely to produce double-yolks.
