Inline avian spray applicator with rapidly-actuating automatic spray nozzles

An automated spray applicator configured for administrating a liquid biologic to young avian animals, comprising:

• a housing;
• a first and a second actuatable automatic spray nozzle, each nozzle comprising a stationary nozzle tip that produces droplets of the liquid biologic, such that greater than 90% of the droplets have diameters sized from about 125 to about 300 microns based on a fluid pressure from about 30 psi to about 80 psi, each stationary nozzle tip produces a 65 degree spray angle at 40 psi, and the first nozzle is positioned to spray towards the second nozzle at about 45 degrees from vertical;
• and
• a programmable spray control module programmed to actuate the first and second actuatable automatic spray nozzles between open and closed positions, wherein the programmable spray control module is in electrical, pneumatic or hydraulic connection with the first and second actuatable automatic spray nozzles;
• wherein the first and second actuatable automatic spray nozzles are in fluid communication with a fluid tank containing the liquid biologic.
