What are the clinical signs or symptoms of avian influenza?

There is a full list on the DEFRA website, but it includes:  swollen head, closed eyes, respiratory distress (problems breathing), lethargy, sudden death, discolouration of face. Ducks and geese may show less or different symptoms, so if you are in any doubt, then you should consult a chicken-savvy vet.
