Egg drop syndrome
Egg drop syndrome is a viral disease of birds, notably chickens, ducks, geese and swans. The phrase "egg drop" refers to the drop in egg production, which is how the disease is usually detected, clinical signs being unreliable. The disease results in thin-shelled or shell-less eggs being laid.
Flock hygiene and minimization of inter-species contact can reduce the incidence of the disease.
In addition to the drop in peak production figures, earlier detection can be achieved. Sentinel birds can be placed in the flock and tested for haemagglutination.
Inactivated vaccines may control the disease, but will not cure it.
