Hundreds of roosters were seized as part of a suspected illegal cockfighting ring in a rural Bay Area enclave that’s known as a hotbed of bird fighting.

Video posted by the Sonoma County Sheriff shows a massive and squalid facility in rural Santa Rosa where Saul Villalobos-Delacruz, a 30-year-old resident, allegedly ran a massive illegal cockfighting operation complete with “slashers, timers, betting slips and conditioning supplements.”

833 roosters were seized, according to authorities.
