“We were more surprised than anything. We don’t feed our chickens anything special,” she said.

“I’m surprised we didn’t hear any cries from the chicken because it’s such a big egg to lay. 

“There’ll probably be people out there saying ‘that’s not such a big egg’, but we’d be happy if this starts a bit of a competition.”

Hen eggs usually weigh between 50 and 70 grams. 

Mrs Farmer said she might make a special pavlova with it, but is also considering boiling it to preserve the special egg. 

She feeds her nine chickens a mix of fresh and cooked vegetables and warm porridge in the morning.

A vegetable garden on the property, full of spinach and silverbeet, is solely for the chickens. 

Mrs Farmer’s husband Alan said one of their chooks had previously laid a large double-yolked egg, but that been nowhere near this one. 

The Farmers have a long way to go to get to the world’s largest egg, however. 

According to the Guinness World Records, the largest hen egg ever recorded weighed 340 grams.
