1. An injection system comprising:
an injection unit comprising:
a first needle assembly comprising a first injection needle and a first needle actuator operably connected to the first injection needle, wherein the first needle actuator is configured to move the first injection needle between an injection position and a retracted position along a first injection axis, wherein the first needle actuator comprises a depth adjustment yoke and support, wherein the depth adjustment and yoke and support are configured to change a location of a distal end of the first injection needle along the first injection axis, and wherein rotation of one or both of the depth adjustment yoke and the support about the first injection axis changes a location of a distal end of the first injection needle along the first injection axis; and
a needle carriage operably connected to a carriage actuator, wherein the first needle assembly is mounted on the needle carriage,
wherein the carriage actuator is configured to rotate the needle carriage about a carriage axis between a standby position and an actuation position,
wherein the first injection needle is configured to contact a bird restrained in a bird restraint when the needle carriage moves into the actuation position, and wherein the first injection needle is positioned subcutaneously in the bird restrained in the bird restraint apparatus when the needle carriage is in its actuation position and the first injection needle is in the injection position,
wherein the carriage axis extends through the first injection axis; and
wherein the bird restraint is operably connected to the injection unit and configured to restrain the bird in a selected position relative to the injection unit.
