A spray delivery system and methods of use thereof, suitable for delivering a
fan-shaped
vaccine spray to birds or chicks held within an open-topped container, comprising
a cover, an elongated guide rail mounted thereon, and a spray head may move reversibly
on the guide rail. The spray head comprises a spray nozzle assembly having a spray
port and optionally a fan-shaped nozzle for delivering a fan-shaped fluid spray.
The cover has an elongated slot that permits the spray nozzle assembly to extend
below the plane of the cover while allowing the spray nozzle assembly to freely
traverse the length of an open-topped container placed beneath the cover. By reversibly
moving the spray head along the guide rail, the spray delivery system can deliver
a substantially uniform fluid spray to an open-topped container with minimal overspray
and reduced fluid wastage.
