Abstract: An apparatus for injecting fluid substances into eggs is disclosed, comprising a plurality of injectors, needles disposed within each of the injectors moveable between a retracted position and an extended injecting position with respect to the injectors, and a bridge assembly for positioning the injectors in alignment with a corresponding plurality of eggs in an egg flat. The injectors rest substantially vertically in openings in a horizontal plate. The openings in the plate are slightly larger than the cross-section of the injectors for permitting the injectors to move vertically within the openings in the plate with respect to the plate. An egg nesting cup is pivotally secured to the lower end of each injector. The injectors are lowered to engage the eggs. When the plate and the injectors are lowered the nesting cups seat against the eggs and the injectors move vertically upward with respect to the plate.

Abstract: Automation of delivery of newborn avian chicks into grow-out houses is accomplished by use of a delivery vehicle which has a powered telescoping conveyor mounted to this vehicle. The vehicle is positioned at one of the personnel doors of a grow-out house and the conveyor extended into the interior of the building. A moving blower is provided at the discharge end of the telescoping conveyor to distribute the chicks over the floor of a grow-out house in such a manner as to prevent piles of chicks from forming.

Abstract: An egg transfer device having an active rotator assembly and a passive rotator assembly pivoted about a common axis above a support table. An automatic clamping device associated with the active rotator assembly is held in an unlocked or open position to allow the active rotator assembly to be loaded with egg flats. After a hatcher tray for receiving the eggs from the egg flats is disposed on top of the egg flats and the passive rotator is rotated thereover, the two rotator assemblies are rotated together about their common axis 180 degrees to their opposite position on the support table. At the same time the automatic clamping assembly is automatically moved into its locked position, thus firmly gripping the tray of egg flats securely into the active rotator assembly as it is being rotated, and stays in its locked position until the active rotator assembly is swung back separately to its original position, at which time the clamping assembly is automatically unlocked.

Abstract: An egg transfer device having an active rotator assembly and a passive rotator assembly pivoted about a common axis above a support table. An automatic clamping device associated with the active rotator assembly is in an unlocked or open position to allow the active rotator to be loaded with a tray of setter egg flats. A hatcher receiver tray in which the eggs from the setter egg flats are to be transferred is disposed on top of the egg flats and, as well, in the passive rotator once it is rotated into an operative position. The two rotator assemblies are then rotated together as a unit about their common axis 180 degrees to their opposite position on the table support.
