1. An injector for injecting at least one substance into eggs, said injector comprising: an injection body for operable coupling to a support in a vertically moveable manner between a raised position and an injection position, said body being equipped with an injection conduit comprising an inlet for the supply of at least one substance to be injected; an injection needle operably coupled to said body and communicating with said injection conduit; and a guiding and protection tube for the guiding and protection of said needle, operably movably coupled to said injection body between a retracted position wherein the needle is projecting with respect to the distal end of said tube, and an idle position wherein said tube surrounds at least the distal part of the needle, said tube being subject to elastic stress by an elastic element towards its idle position and being movable to its refracted position by pressing its distal end against an egg when the injector is in the injection position, wherein said injector is equipped with control means for controlling the supply of said injection conduit with at least one substance, said guiding and protection tube cooperating with said control means to disable the supply of said injection conduit when said tube is in the idle position and to enable the supply of said conduit when said tube is in the retracted position.
