It is the 36th country in the world to be hit with avian-flu since the end of October last year.
It is the latest case to hit Europe as the pandemic has literally spread around the world in the last couple of months, and some of the more highly pathogenic avian influenza virus having spread to people in Asia resulting in death for some.
Europe's struggle with highly pathogenic avian influenza (HAPI) has seen the disease now breach Belgium, a country free from bird flu outbreaks for seven years.
The HAPI strain H5N8 was detected in a backyard holding in the Lebbeke province, a town under 30 kilometres from the Netherlands, a country that has culled more than 200,000 birds to combat bird flu.
No chickens have been infected by bird flu as the farm is not a commercial poultry operation, according to Belgium's Federal Agency for the Safety of the Food Chain (AFSCA).
A disease update from the World Organisation for Animal Health (OIE) said the species of birds infected included goose, ducks, guinea fowl and pheasant.
In total, 55 birds were humanely culled.
