When chickens become sick with Avian Influenza, one of the first signs of illness is that they stop laying eggs. In High Pathogenic Avian Influenza (HPAI), the more severe form of the virus, the illness is very sudden, egg production stops, and many of the birds will die from the disease. If HPAI were to be identified within a commercial flock in the United States, at the first sign of illness, the farm would be immediately quarantined. If eggs are laid after the onset of illness (at most one or two eggs per hen), they will be of inferior quality and would be discarded during the washing, grading and inspection process. The eggs will not even be sent to the packing plant since the farm is under quarantine.
