A recent HSUS investigation revealed a Costco egg supplier cramming chickens into tiny cages, forcing birds to live in cages with the decayed, mummified corpses of their dead cage-mates, and engaging in other inhumane practices that are bad for animals and food safety. This is in stark contrast to the happy hens and green fields depicted on egg cartons sold at Costco.
Costco is not the only retailer using these types of eggs. Many other retail businesses, because they are able to make much more money from egg production when birds are caged, are also retailing this type of produce.
