Laboratory tests were carried out at the holding in Fenton Barns, Drem, earlier this week following the investigation of the suspected presence of the disease.
The Scottish Executive, Defra and the State Veterinary Service are currently undertaking thorough epidemiological assessments to determine the source of the disease and the level of risk it may pose to other poultry. Restrictions have been put in place and poultry on the premises will be culled in line with EU requirements. A 3km protection zone and a 10km surveillance zone have been established.
Keepers of poultry in the areas are being contacted with information on disease and how to maximise biosecurity protection for their flock.
