A potentially fatal virus is spreading among birds. The director of a bird sanctuary found an herbal supplement that claims to reduce susceptibility to the virus. The director decided to test the supplement by having his staff put it in the water of every other birdbath in the sanctuary. Can this be considered a randomized experiment?
