As cages are being phased out, an egg-producing giant is investing heavily in its free-range facilities. Otago Daily Times's Shawn McAvinue visits two Zeagold Nutrition facilities in East Otago, including a free-range farm near Moeraki, which supplies some of the 650,000 eggs graded in Waikouaiti every day of the year, and finds happy hens and an industry in its final stage of reset.
As the last of the hen cages are being phased out of farms across New Zealand, an egg-producing giant continues to invest in its free-range facilities in Otago.
Zeagold Nutrition agribusiness general manager Judith Mair, of Dunedin, said the company had 1.3 million hens laying eggs, making it the biggest egg producer in New Zealand.
Its network of egg farms in New Zealand included three free-range systems in Otago - one in Glenpark, near Dunback, one near Hampden in North Otago and another at Hillgrove near Moeraki in East Otago.
In the past 15 years, Zeagold had invested "a lot" in free-range farming in Otago, Mair said.
"The exiting of cage farming is one of the biggest transformations in the poultry industry and we are working through the final wave of that exit," Mair said.
The phasing out of cages was nearly complete at Waikouaiti.
In the North Island, Zeagold was investing in new barn facilities and a new free-range farm.
"They are exciting developments, they are beautiful farms."
The company was proud of its facilities, its utilisation of "the best of European technology" and providing aviary systems that allowed its birds to demonstrate natural behaviours.
"We are serious about good farming practice and creating sustainable environments."
About 4500 trees and shrubs had been planted on the ranges at Hillgrove to provide shelter from weather and protection from predators, such as hawks.
Gravel was placed outside the sheds, so hens could clean their feet before entering indoors, to ensure the sheds remained as clean as possible.

The hens were the "heartbeat of the company" and each flock had its own personality and temperament.
The data showed patterns to alert staff to changes in hens' behaviour.
After eggs were graded and packaged in Waikouaiti, some were trucked daily to places between Queenstown, Timaru and Invercargill.
Most went to distribution hubs in Christchurch and Auckland.
The company supplied about 2 million eggs to the Christchurch hub annually, she said.
A vertically integrated supply chain ensured control of the complete process, including producing chicken feed at a mill in Waikouaiti, buying day-old chicks from a company it part-owned and then rearing them at Hillgrove before moving them to aviary sheds on another part of the same farm, where the hens spend the rest of their productive lives.

After the hens were euthanised, they were rendered to feed for another type of farm animal.
Hen manure was harvested weekly on the farms and was all contracted for use as fertiliser on farms.
The company was always investigating new ways to be sustainable, such as how to obtain a power source from the wind which blows down Trotters Gorge.
"We are looking at how to create a self-supporting system. We've got a bird that provides a sustainable source of protein so how do we create a sustainable system to support that protein source?"
Mair said challenges in the industry included Covid-19 market impacts and staff shortages.

Automation could detect hairline cracks in eggs and automatically reject them so they could be made into pulp or separated into yolk and whites.
However, the market "slumped" when Covid-19 affected the food sector and "slowed" the industrial sector.
Before Covid-19 closed borders, backpackers on working holiday visas had jobs on their sites including helping build facilities at Hillgrove in 2019 and 2020.
"We are really looking forward to those borders opening up and getting a few more people to help the team."

At the egg-grading facility at Waikouaiti, eggs were packaged under its brands Woodland and Farmer Brown.
Eggs produced on Hillgrove also supply clients including McDonald's.
McDonald's managing director David Howse said McDonald's supplied 10.6 million free-range eggs to its restaurants in New Zealand last year.
Some of the eggs were supplied by Zeagold Nutrition's farms in Waitaki and the rest were from Otaika Valley Farms in Northland and the Bay of Plenty.
Zeagold Nutrition Waikouaiti site manager Neville Kennedy said the eggs graded and packed at the site were from the farm on-site, the three free-range farms in the Waitaki area, and occasionally from a farm in Fernside, Christchurch.

Every free-range egg the company produced was graded and packed in Waikouaiti for distribution.
At the facility, nearly 80 staff worked between 6.30 am and 3 pm, grading and packing about 650,000 eggs every day of the year.
"We've asked the chickens to stop at Christmas and Easter but they just won't listen."
