The present invention relates to a method for spectroscopical in-ovo gender determination of fertilized and incubated bird eggs comprising the steps of: a. providing a number of passages in an egg shell of an egg for allowing entrance into an interior of the egg and/or exit from the interior of the egg of electromagnetic waves suitable for spectroscopy, b. introducing electromagnetic waves into the interior of the egg c. detecting electromagnetic waves exiting the egg; d. analysing, by spectroscopy, of the exiting electromagnetic waves at at least one passage of the number of passages; and e. determining the gender of a chicken embryo.

Method for processing a plurality of avian eggs, in particular unfertilized eggs, including:—conveying at least a first egg (E1) having a first eggshell color and a second egg (E2) having a second egg shell color along a conveying path, the first egg shell color being different from the second egg shell color;—illuminating the first egg (E1) with an illumination beam (B) of near infrared light, wherein at least part of the light is transmitted through the egg (E1) and is detected by a near infrared light detector (5);—illuminating the second egg (E2) with the illumination beam (B) of near infrared light, wherein at least part of the light is transmitted through the egg (E2) and is detected by the near infrared light detector (5); processing light detection results of the infrared light detector (5) for determining a condition of the shell of each of the eggs (E1, E2); wherein the illuminating of the eggs (E1, E2) and/or the detection of transmitted light is carried out under substantially the same illumination and/or detection conditions, respectively.

A device for the in-ovo determination of the sex of a fertilized bird egg, having a light source for emitting excitation radiation for exciting fluorescence in a region inside the bird egg, a spectroscopic apparatus for analysing, in a temporally and/or spectrally-resolved manner, fluorescence radiation emitted from the region inside the bird egg, an evaluation unit for determining the sex from the data determined by means of the spectro-scopic apparatus and a measuring head for jointly transmitting the excitation radiation into the bird egg and receiving the fluorescence radiation from the bird egg. The measuring head has an optical fibre system with a head end for transmitting the excitation radiation and receiving the fluorescence radiation.
