Abstract:
1. An injection head for injecting at least one injectable substance into an egg having a shell and a shell membrane, the injection head comprising: an injector support positionable above the egg; at least one injector coupled to the injector support, the at least one injector comprising: a fixed chassis, the injector support movably coupled to the chassis; and a main actuator for shifting the injector support between a high position and a low position; wherein the main actuator is controlled to shift the injector support from its high position to its low position so the injection needle in the raised position pierces the shell of the egg with a first penetration force and the individual actuator is controlled to shift the injection body from its raised position to its injection position so the injection needle pierces the shell membrane of the egg with a second penetration force, the second penetration force being lower than the first penetration force.
