Abstract

The invention relates to a method and a device (1, 100) for determining the sex of fertilized, nonincubated bird eggs (13, 130), where an egg (13, 130) has a solid egg shell (14), an egg yolk (2) which is surrounded by the egg shell and further egg integuments and a blastodisc (3) associated with the egg yolk (2), and where a probe (4, 40) for measuring a spectrum is introduced through a hole (17) of the egg shell (14) towards the blastodisc (3) with blastodisc cells (23), with the following steps: —positioning of the probe (4, 40) in the region of the blastodisc (3), —spectroscopic in-ovo characterization of the blastodisc cells (23), and —identification of the sex by an automatic classification of spectra.
