Stillmore, GA (AP) — An animal protection organization has raised objections to convicted felons being used to process chickens at a south Georgia poultry plant whose workforce was decimated by a crackdown on illegal immigrants working there.People for the Ethical Treatment of Animals said Wednesday that it was concerned that criminals with violent pasts could be among the workers being bused from a probation center.PETA said it wanted to point out “that chicken slaughterhouses are notorious for animal abuse and that staffing the plant with violent criminals is begging for violations of Georgia’s cruelty-to-animals laws.”
