The case is thought to have originated in wild birds, and there are no recommendations that flocks be isolated from their free-roaming counterparts.
Representatives from the National Farmers Union Scotland have also told avian cultivators to make sure they disinfect vehicles and equipment rigorously.
In a statement, NFU Scotland said: “Urgent message for poultry keepers.
“Low pathogenic Avian Influenza (AI), thought to have been contracted from wild birds, was confirmed in a Scottish free range laying flock at the end of last week.
“Please ensure highest levels of biosecurity at this time.”
In December, all 27,000 birds at a commercial poultry farm in Suffolk were culled after a number were found to have the H5 strain of avian flu, identified as “low pathogenic”.
