An egg producer from northern NSW has differentiated its product from other "free range" eggs, to show the hens were raised on grass.
Therese and Andrew Hearne have 250 chickens roaming around their 22-hectare property at Hollisdale in the Hastings Valley.
Therese says free range on dirt is a completely different product.
"Many free range eggs do not have pasture and green grass to peck and do what a normal chicken does," she said.
"So that's why we specifically call them pasture-raised eggs, so that it takes away the mystery of whether or not they're just roaming around a piece of dirt or actually in their natural environment of grass."
Therese has welcomed Woolworths' plan to phase out caged eggs by 2018, but questions why it can't be done sooner.
"There's a lot of food that gets produced in that five years that people will not get the benefit of having free range eggs," she said.
"I understand why it's like that, but then why didn't they do it seven years ago?"
She says the stocking rate of chickens per hectare for free range egg production should be 1,500, and that 20,000 birds in that same space would be "pretty horrific".
