Agriculture officials in Iowa say bird flu will claim an additional four-million chickens on two more farms in a county already hit hard by the disease.
Officials say the latest outbreak of avian influenza has hit chickens at two farms in Iowa’s Wright County, although tests for the disease still need final confirmation.
The county earlier reported a farm with almost three-million chickens affected.
Iowa's chicken loss is approaching 25 million. That’s more than 40 percent of the state's egg-laying flock.
