Egg tray (1) for supporting eggs in an incubation chamber, the egg tray comprising a first grid (10) extending in a bottom plane (P), the first grid comprising one or more adjacent rows with slanted ribs extending from one side of the row to the other to form a plurality of adjacent openings (13), wherein an opening (13) defines an egg accommodation, wherein the ribs are configured for contacting an egg at a middle part (14) of the ribs between two rib ends in order to support an egg in the egg accommodation.

An incubator (10) includes: (i) a housing (12) defining a chamber (14); (ii) an air inlet (16) for introducing air into the chamber (14); (iii) a first air outlet (18) for discharging air from the chamber (14), the first air outlet (18) being spaced from the air inlet (16); (iv) a stack of operatively vertically spaced first trays (22) disposed within the chamber (14), between the air inlet (16) and the first air outlet (18); and (v) a first means for tilting the stack of first trays (22) on a plane substantially perpendicular to the direction of operative airflow from the air inlet (16) to the first air outlet (18). A stack of operatively vertically spaced first deflectors (26) are disposed operatively upstream of the first trays (22) for, in use, dividing the airflow from the air inlet (16) to the first air outlet (18) into streams of airflow directed over the first trays (22); and the incubator (10) further includes a second means for tilting the first deflectors (26) on a plane substantially perpendicular to the direction of operative airflow from the air inlet (16) to the first air outlet (18), in use to align the first deflectors (26) with the first trays (22).

An incubator includes a housing defining a chamber, an air inlet for introducing air into the chamber, and a first air outlet for discharging air from the chamber. The first air outlet is spaced from the air inlet, and a stack of operatively vertically spaced first trays is disposed within the chamber between the air inlet and the first air outlet. A first tilting mechanism is provided for tilting the stack of first trays on a plane substantially perpendicular to the direction of operative airflow from the air inlet to the first air outlet. A stack of operatively vertically spaced first deflectors are disposed operatively upstream of the first trays for dividing the airflow from the air inlet to the first air outlet into streams of airflow directed over the first trays. The incubator further includes a second tilting mechanism for tilting the first deflectors on a plane substantially perpendicular to the direction of operative airflow from the air inlet to the first air outlet to align the first deflectors with the first trays.

The invention relates to a tray for containing a number of eggs in an incubation chamber, the tray comprising a number of egg accommodation spaces in which space an egg is able to be hatched, and at least one passage for a chicken through which passage a chicken hatched from said egg may pass through the tray and enter a chicken accommodation space located below the tray.

An egg placing machine cassette for receiving eggs to be laid upon a surface. The eggs being received in a two-dimensional array and wherein the cassette comprises a base portion, side walls extending from a first end of the base portion and a lid portion that is connected to a second end of the side walls, that second end being distal from the base portion. The cassette is provided with a first opening mechanism, by which a setter tray is able to be placed inside the cassette. The cassette is further provided with a second opening mechanism, in which the lid portion can be partially and/or progressively opened to allow a predetermined number of eggs to be removed therefrom.

The present disclosure relates to methods and systems in egg hatching, based on hatching eggs in a tray (2), comprising arranging eggs in a pattern in or on the tray, comprising egg supporting positions and holes together defining the pattern, wherein the holes are dimensioned to allow chicks (27) after hatching to pass there through into a crate (4), detecting at least one of numbers of unhatched eggs (22) in or on the tray; numbers of dead chicks in the crate; and numbers of objectionable chicks in the crate, and supplementing or removing chicks to or from the crate in correspondence therewith.

The invention relates to a tray for containing a number of eggs in an incubation chamber, the tray comprising a number of egg accommodation spaces in which space an egg is able to be hatched, and at least one passage for a chicken through which passage a chicken hatched from said egg may pass through the tray and enter a chicken accommodation space located below the tray.

Disclosed is a cradle for the incubation process of eggs in hatcheries, for the incubation of eggs in a cradleroora and optionally the hatching of the chicks, the cradle including an outer edge and an inner structure with a. number of positions to receive eggs, whereby the cradle includes a tiltable inner structure and a stackable outer edge. Also disclosed is a stacking of the, cradles, a cradleroom, incubation process, and method for the incubation of eggs.

Disclosed is a device for contactless measuring of an embryo's heart rate in an egg whereby infrared light is sent in the egg by one light source, and the reflection of that light is detected by one or more light sensors and converted into a signal representative for the heart rate, whereby a shield is provided to avoid light that is reflected on the egg shell interfering with the light sensors. The shield is provided at the light source and not at the light sensors, whereby a light tube is provided between the light source and the egg and the light tube is internally dimensioned and positioned such that a focused light spot is directed on the egg, and the light tube is dimensioned and positioned such that light reflected on the surface of the egg on the level of the light spot cannot directly reach the light sensors.
