Abstract
To determine the sex of a bird egg, a hole is produced at the blunt end of the bird egg, wherein the hole affects the calcareous shell and the outer shell membrane, whereas the inner shell membrane remains intact. In the region of the hole at the blunt end, beneath the intact inner shell membrane, at least one blood vessel is registered and the blood therein is excited by means of a preset incident radiation, the back-scattered radiation of which blood is measured, detected and evaluated for the sex determination.
