Bird flu has been detected at a second farm in western Victoria, 130km west of the farm where 400,000 chickens are being euthanised after the outbreak was first detected.
The farm in Terang is linked to the Meredith egg farm, about 40km north-west of Geelong, where the mass chicken cull and disposal is taking place after an outbreak of the highly pathogenic H7N3 strain of avian influenza.
