The case was found to be a non-notifiable strain of avian influenza.
Restrictions have been lifted on a Scottish farm which had a suspected case of bird flu.
A Scottish Government spokesman said a mild strain of non-notifiable avian influenza had been found following routine investigations, and restrictions on the site have now been lifted. NFU Scotland said the case in a free-range laying flock was thought to have been contracted from wild birds.
A union spokesman said: “All the possible steps must be taken to ensure that poultry, and other captive birds, are protected against contact with wild birds.
“It is important to avoid the transfer of contamination into and between premises and to minimise the movement of people, vehicles and equipment to areas where captive birds are kept.”
The affected farm is believed to be in the Scottish Borders.
