Authorities in California raided an illegal cockfighting event last weekend.
More than 200 people were at the event when police arrived at a home in Jurupa Valley, about 50 miles east of Los Angeles. Officers found "multiple deceased or severely injured birds" at the site, and another 143 roosters in cages.
All of the birds were "humanely euthanized', police say.
“The birds must be euthanized because Animal Services cannot adopt out such birds as they are valuable and they would almost always end up back in a cockfighting ring. They are not suitable as pets,” the Riverside County Sheriff's Department said a statement.
One man, who said he owned the birds, was cited for possession of fighting blades.
