Abstract: The present invention provides systems for the injection delivery of at least two fluid doses to a small bird by penetrating the skin of the recipient bird with at least two injection needles. It is then possible to simultaneously inject drugs, or other fluid vaccines that do not mix well or whose mixture would be detrimental to the stability or efficacy of the active ingredients therein. The present invention provides a novel injection needle support for connecting the injection needles to dose distributors and fluid supply containers while maintaining the injection ends of the injection needles in a substantially parallel arrangement.
