Was reading a news article about this Pennsylvania flock and it says -
A duck and chickens from a flock in Upper Mount Bethel Township in Northampton County were confirmed to be infected after a dead turkey vulture was found on the property. Wild birds are known to be the source of the infection elsewhere.
