Biosecurity for the hatchery must begin at the breeder farms producing the hatching eggs. The production of top grade and healthy chicks/poults from the hatchery depends on careful attention to detail, starting with the arrival of the breeding stock from NPIP participating hatcheries on the farm, testing arriving chick/poults papers for Salmonella, to the collection and dispatch of hatching eggs, to the delivery of the chicks to their final destination.
