Early Identification

The Raman-spectroscopic Method

In the Raman-spectroscopic method, the determination of sex takes place with the support of an optical measuring procedure on the fourth day of incubation. First, the air cell within the egg is detected, the shell is then perforated with a CO2 laser and the lid of the shell is lifted. After the sex of the embryo has been determined, the shell is re-sealed. The eggs classified as females are then returned to the incubator and the male eggs are used for further processing in the industry.
