SIBLEY, Iowa (AP) – Iowa farmers who have been dealing with thousands of dead chickens attracting flies for weeks are frustrated with the government’s response to the ongoing bird flu outbreak. The Des Moines Register reports several chicken and turkey farmers expressed their concerns at public meetings in northwest Iowa Saturday.

Merlin DeGroot says he’s waiting for government crews to dispose of his dead chickens, but the agencies involved haven’t coordinated plans well. Iowa Agriculture Secretary Bill Northey says the size of the bird flu outbreak is unprecedented and the government is working to respond.

More than 25 million chickens, turkeys and ducks have been killed in Iowa, and it has taken time to find places to dispose of their carcasses. Two landfills in the state recently agreed to take birds.
