The family that operates a British Columbia ostrich farm facing a federal cull says it may look into the process of moving the birds to the United States as a "last resort."

RCMP say they are investigating after a second ostrich was found dead in suspicious circumstances on a B.C. farm where roughly 400 of the birds have been ordered killed by the Canadian Food Inspection Agency (CFIA).

RFK Jr and Dr Mehmet Oz are backing an ostrich farm in British Columbia as it seeks to stop a cull ordered after a bird flu outbreak.
