The World Society for the Protection of Animals has launched a new "Choose Cage-Free" campaign in the United States and Canada.
The advertising and social media campaign stated keeping egg-laying hens in cages is inhumane and urges consumers to buy cage-free eggs.
Some 95 percent of U.S. and Canadian egg-laying hens -- more than 300 million hens -- live in small cages without sufficient room to spread their wings or turn around, according to WSPA.
"It is one of the cruelest and most inhumane practices in modern farming," Anne Lieberman, executive director of WSPA USA, said in a news release.
The organization is headquartered in London and has offices in New York and Toronto.
"We are pro-farmer and work to engage every link in the supply chain to drive change," Lieberman said.
Asked if WSPA supports the Humane Society of the United States and United Egg Producers' efforts for federal legislation to enlarge cages, Lieberman said WSPA "respects all efforts to improve the quality of life for hens, but does not believe hens should be confined in any cages."
