Bird flu outbreak confirmed at Northern Colorado egg-laying facility

State officials have confirmed an avian flu outbreak in Northern Colorado. Agriculture officials said the outbreak occurred in a commercial egg-laying facility in Weld County.

The facility houses more than a million chickens. 

The state said the new cases are a reminder that the virus is actively circulating in the state. 

In total, more than 11 million chickens are affected. 

Last week, the Governor's Office of Colorado issued a disaster declaration for the outbreak.
