In the largest global investigation ever, The Open Wing Alliance reveals never-before-seen footage of systemic animal abuse and public health risks in cage egg factory farming. Alongside footage from 36 other countries, the exposé includes footage from a colony cage factory farm in New Zealand.
New Zealand— June 17 2025 — " The sound of thousands of trapped chickens, the industrial fans cranking and the stench of waste is beyond words ', says a volunteer investigator from Grassroots Campaigns NZ. ' It's hell inside."
This is the description animal welfare investigators gave about what they captured at an Auckland colony cage factory farm. Their footage was given to the Open Wing Alliance, a global coalition of nearly 100 organisations established by The Humane League, in collaboration with We Animals and Reporters for Animals International. Together with Animals Aotearoa, the united group has just released the largest ever investigation into industrialised egg farms in 37 countries. In never-before-seen footage, including from New Zealand, supported by an open letter backed by 100 celebrities.
" The shocking footage exposes widespread abuse of egg-laying hens trapped in filthy, overcrowded cages, with evidence of injured birds, rotting carcasses, disease-ridden conditions, and more. This investigation comes as bird flu sweeps across every continent, jumping from farmed birds to wild animals and even humans", says Jennifer Dutton, Corporate Relations Specialist at Animals Aotearoa.
Footage from 37 countries, including:
Argentina, Australia, Brazil, Bulgaria, Canada, Chile, Colombia, Estonia, Finland, France, Georgia, Hong Kong, India, Indonesia, Israel, Italy, Japan, Malaysia, Mexico, New Zealand, Nigeria, Norway, Peru, Philippines, Poland, Portugal, Romania, Russia, Slovenia, South Africa, Spain, Taiwan, Thailand, Turkey, United States, Vietnam and Zimbabwe.
Key findings from the global exposé include:
Hens confined in battery and enriched/colony cages, giving each chicken only the space of an iPad, or less, to live their entire life;
Automated systems leave dead bird carcasses trapped in cages with living hens;
Live hens abandoned in manure and waste pits, and eggs found in manure before sent to shelves;
Birds unable to stand upright or spread their wings;
Unsanitary conditions that promote disease spread, like avian influenza.
This massive coordinated worldwide campaign is focused on spotlighting multinational brands dragging their heels on fulfilling corporate policy to transition away from cage eggs in their supply chains. The vast majority of food corporations around the world publicly committed, a decade ago, to remove cages from their egg supply chains, with global companies like The Hershey Company, Hormel Foods, Famous Brands, and Barilla already fully cage-free. However, food companies like Walmart, Zensho Holdings and Inspire Brands (parent company of Dunkin' and Baskin-Robbins) continue to profit from sourcing eggs from hens raised in outdated, cruel cages. In New Zealand, hospitality giant Best Western Hotel chain was recently targeted by protestors highlighting the multinational's lack of transparent reporting on its global cage-free progress, supported by a petition.
Since 2023, when battery cages were outlawed in Aotearoa, there has been a disinformation campaign by the factory farm lobby to mislead caring New Zealanders about the continued domestic production of cage eggs. While battery cages are no longer in use, colony cages are. Eggs sold at retail level from these colony cage systems don't contain the word 'cage' anywhere on the packaging. Following a number of complaints, the Commerce Commission is currently conducting a compliance project to assess whether colony eggs are a breach of the Fair Trading Act.
In addition to cage eggs being sold under misleading labelling, the import of liquid eggs from battery cages is a significant problem. Over 80% of New Zealand's liquid eggs, used largely in food manufacture, are imported from China and Australia where egg-laying hens are kept in battery cages. Produced using methods illegal here, they are added into Kiwi foods and quietly sold to the caring public who are unaware.
Consumers around the world are increasingly demanding transparency and ethical treatment of animals in food production, and they won't stand for further risks to our global public health. Over 100 celebrity figures signed an open letter urging food corporations to end the use of cages in their global supply chains. This investigation sends a powerful message: the real cost of eggs is paid for in animal and human health. It's time for corporations to put an end to cruel and risky caged confinement.
