What are the symptoms of avian flu in poultry?
Symptoms of a low pathogenic form of avian flu virus in poultry can include ruffled feathers, lower feed consumption, and a drop in egg production, or there may be no symptoms at all. By contrast, the highly pathogenic H5N1 virus causes severe illness and often kills the bird within 48 hours and the first sign may be dead birds. More than 90% of birds in a flock may die from infection with highly pathogenic avian flu viruses.
