"But now the bureaucrats have decided the gap has to be 350mm. That means we've got to take the front walls of those sheds to create the new width they're demanding," he said.
Another change involves the size of the sheds and on that basis it means the Higgins family will have to cut the numbers of birds in each shed by 500.
"That's going to cost us more money," Mr Higgins said.
The changes have come from the National Animal Welfare Advisory Committee which passed its recommendations to Nathan Guy, the Minister of Primary Industry. Mr Higgins said committee appeared to be copying European standards and although he had no issue with that, he was upset with changes being made retrospectively and costing his business money.
"These hidden costs keep popping out of the woodwork," he said.
Mr Borrows told the Chronicle he understood the family's concerns.
"They built to the specifications they were told to but then changes were made. From a local MP's point of view it isn't good enough," he said.
"This has a $50,000 cost on their business but there's no justification for it."
Mr Borrows said demanding a 10cm increase in the height of access in the sheds meant a "really big" compliance cost and made no sense.
"Obviously, regulations need to be consistent.
"But SPCA ... our animal welfare watchdog, is saying the regulations are fine but officialdom is saying they're not."
He said the matter would be taken up with the minister. The Higgins family made the move to free range production before pending changes to the country's caged bird regulations.
They have already secured an endorsement from the SPCA and have bought more neighbouring land to increase the number of sheds for more birds.
Eventually there will be 18 new 600sq m sheds for the free-range chickens.
At the moment they have about 15,000 free-range birds laying about 1100 dozen eggs a day but that output could triple in future.
