The Department for Environment, Food & Rural Affairs (Defra) said: “A 3km protection zone and 10km surveillance zone have been put in place around the premises. All poultry on the premises will be humanely culled.”
It comes a day after fears of a suspected outbreak of the highly pathogenic avian influenza (HPAI) in commercial poultry at premises near North Thoresby, East Lindsey, Lincolnshire, was ruled out.
