We took in a stray chicken who must have been an asymptomatic carrier of a respiratory disease as 7 of our 30 hens have died in 10 days, and all but one or two seem to be infected and have stopped laying. I can't seem to find a veterinarian who sees chickens in my area and the local extension office chicken person did not call me back. Online research indicates the remaining flock should be culled??? If that is necessary, then what kind of sanitizing does the hen house and run need before introducing new pullets? My spring chicks are fast outgrowing their pen in the garage! Does anyone know of a vet who will see chickens in Homer Glen, Will county?
