The Humane Society of the United States (HSUS) has released investigative footage recorded by an undercover agent, exposing animal cruelty at four factory farms owned by the country’s second- and third-largest egg producers—Rose Acre Farms and Rembrandt Enterprises. The four facilities investigated confine about 10 million birds, combined. Some of the animal abuses include cruel handling resulting in broken bones, untreated prolapsed uteri, and failure to maintain manure pits, resulting in bird blindness from ammonia fumes. The results of the investigation have been picked up by mainstream media outlets, such as Reuters and The LA Times.
