On a chilly, early morning in January 2019, a group of animal rights activists descended upon a poultry farm in central Texas. Donning plastic gloves, medical masks, hazmat suits, and T-shirts emblazoned with “Meat the Victims,” they slipped through the unlocked door of a massive, windowless barn.

Inside, they found 27,000 chicks densely packed across the floor, like “just a sea of yellow,” recalled Sarah Weldon, one of the activists. “There were a lot of chicks that were already deceased, in various stages of decomposition,” she said. “Some were so deformed you couldn’t even tell they used to be baby chicks, just fluffs of feathers.”

Activists with Meat the Victims, a decentralized, global movement to abolish animal exploitation, later uploaded gruesome photos of injured and dead chicks to social media platforms. This is how, Weldon suspects, the police identified her and issued a warrant for her arrest, along with 14 other activists. She was charged with criminal trespassing, a Class B misdemeanor, and quickly turned herself into jail.

The FBI has been collaborating with the meat industry to gather information on animal rights activism, including Meat the Victims, under its directive to counter weapons of mass destruction, or WMD, according to agency records recently obtained by the nonprofit Animal Partisan through Freedom of Information Act litigation. The records also show that the bureau has explored charging activists who break into factory farms under federal criminal statutes that carry a possible sentence of up to life in prison — including for the “attempted use” of WMD — while urging meat producers to report encounters with activists to its WMD program.
