A system for determining the gender and/or fertility status of avian eggs including a sampling apparatus and an electromagnetic radiation transmitter and detector. In certain embodiments, the transmitter operates in the terahertz range. The sampling apparatus can be coupled to an avian egg. The sampling apparatus includes a vacuum source, a gas collection device, and a membrane that can be positioned in the passageway coupling the vacuum source to the gas collection device. The membrane is capable of capturing volatile organic compounds. The sampling apparatus applies a vacuum from the vacuum source to the gas proximate to the avian egg and directs the gas captured from the vicinity of the egg toward the membrane. Subsequently, the membrane is positioned within the electromagnetic radiation emitted by the transmitter, generating a spectrum which can be analyzed to determine whether the egg is fertile or infertile, and if fertile, whether the egg is male or female. In an embodiment, the captured volatile organic compounds are transferred to a sample chamber where the captured gas is analyzed.

An incubation tray is disclosed, including an enclosure with a plurality of egg placements for carrying eggs for incubation within an egg incubator. The incubation tray includes a tester unit including plurality of inspection modules in the enclosure associated with the plurality of egg placements. The inspection modules, each includes radiation emitter(s) and sensor(s), and are configured and operable for respectively inspecting the plurality of eggs located in the egg placements, by irradiating the eggs with radiation from a lateral side of the eggs and measuring a radiation response coming in response to the irradiation from a lateral side of the eggs, giving rise to measured data indicative of conditions of the eggs. The measured data may be processed to determine dynamic and static parameters of the radiation response from which a physiological development stage, and growth of the embryos within the eggs can be estimated.

A system and method to promote biological responses within incubated eggs using lighting devices within an incubation chamber. A light supporting device is installed within the incubation chamber in spaced relation to an incubation device housing a plurality of eggs. The light supporting device is positioned to direct light at pre-determined wavelengths into the interior cavity of the incubation device to irradiate the plurality of eggs to promote a biological response within the eggs.

Disclosed is a device for the automatic removal of rejected eggs from an incubation tray, whereby the device includes a suction power above the egg to suck up the egg, and the device further includes a blowing power against the bottom of the egg to blow away the egg, whereby the blowing power blows an air flow or overpressure against the bottom of the egg. Also disclosed is a method for the automatic removal of one or more rejected eggs from an incubation tray.

Method and a device for the optical in ovo sex determination of fertilized and incubated birds' eggs. The method includes monitoring formation of at least one identifiable blood vessel, creating a hole in the shell of the egg, finding and irradiating the blood vessel with at least one laser beam source emitting an excitation wavelength, recording backscatter radiation of the irradiated blood vessel and evaluating backscatter radiation from recorded spectral intensity of fluorescence radiation in a spectral range redshifted to an excitation wavelength. Sex-specific properties of male and female blood are contained in the intensity and spectral profile of the recorded fluorescence radiation. where intensity levels for male blood has an evaluable value distinct from that of female blood. Further, determining the sex of the bird egg from difference values of the fluorescence intensity and displaying the sex determined for the embryo in the egg.
