Title: METHOD AND DEVICE FOR INTRODUCING AN OPENING INTO THE CALCAREOUS SHELL IN THE REGION OF THE BLUNT END OF INCUBATED BIRD EGGS WITH AN EMBYRO
Abstract:
The invention relates to a method and a device for introducing an opening into the calcareous shell of incubated bird eggs, having embryos contained therein, in the region of the blunt end of the incubated eggs. Within the region of the blunt end, there is an outer membrane and an inner membrane, between which there is an air chamber. The device comprises: a retaining device, on which the incubated bird eggs are placed with the pointed end facing downwards, wherein the embryo is positioned adjacent to the inner membrane; a first detection device that is configured to determine the position and geometry of the air chamber; and an opening device that is configured to introduce an opening into the calcareous shell at the blunt end of the incubated bird egg above the tensioned inner membrane. As a result of the opened calcareous shell, a sex determination of the embryo can be reliably carried out.
