Those viruses can infect chickens, turkeys, pheasants, quail, ducks, geese and guinea fowl, as well as a wide variety of other birds. According to the Animal and Plant Health Inspection Service (APHIS), USDA, migratory waterfowl have proved to be a natural reservoir for the less infectious strains of the disease.
