The confirmation of bird flu at another Iowa egg-laying farm will force the killing of more than 5 million chickens, officials said Friday, March 18, 2022. Spread of the disease is largely blamed on the droppings or nasal discharge of infected wild birds, such as ducks and geese, which can contaminate dust and soil. (AP Photo/Charlie Neibergall, File)
