 Walmart's cage-free eggs will not come from free range producers, but rather industrial-scale farms where the birds will be allotted between 1 and 1.5 square feet each, a stressful arrangement which can cause cannibalism.Unlike battery cages, the systems Walmart's suppliers will use allow the hens to move around, but relative to battery cages they have higher hen mortality rates and present distinct environmental and worker health problems.On November 28, 2016 Paola Gaviño in coordination with the animal protection NGOs, The Humane League and Mercy For Animals, launched a multinational campaign to raise awareness of Walmart’s failure to produce a policy to source 100% cage-free eggs throughout Latin America.
