  • Patent number: 6196159
    Abstract: A method and apparatus for incubating a poultry egg by placing the egg in a random orientation into an opening of substantially elliptical configuration provided in an egg support, placing the egg support into a receiving tray provided with an elevation facing the opening such that the egg engages the protrusion, reciprocally moving the egg support relative to the tray thereby to impart to the egg an optimum incubating orientation, subjecting the egg to incubation while maintaining the orientation and rotating the egg about its major axis.

  • Patent number: 5568791
    Abstract: A poultry egg incubation method and an apparatus for carrying out the method. Eggs are initially placed in openings of substantially egg-shaped contour provided in an egg support which is thereafter placed in a hatching bin with the eggs out of contact with the bin. The bin is then placed in an incubation container or cart. For purposes of incubation the support is lowered to place the eggs in point contact with the bin so that relative movement between bin and support causes rotation of the eggs without disturbing their position within the bin. Controlled humidifying and ventilating equipment is provided for providing stable climatic conditions.
