Abstract: 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.

Abstract: 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.

Abstract: This invention relates to a method for promoting growth of young chicken comprising the step; offering feed in a layered manner in subsequent order of pellet-size for adjusting the pellet-size to the size of the young chicken during a whole brooding cycle for the feed being attractive during the whole brooding cycle as perceived by the young chicken.

Abstract: The invention relates to the use of a cyclone separator for separating keratin particles originating from poultry out of a gas, in particular air. The separated particles comprise down particles. The invention furthermore relates to a climate chamber for hatching eggs and/or keeping poultry. Said climate chamber comprises a substantially closed compartment having two opposite side walls provided with one or more passages; as well as a substantially closed duct which extends outside the compartment and connects one of said side walls to the other of said side walls so as to form a substantially closed circuit together with the compartment. Said climate chamber furthermore comprises a cyclone separator, the inlet of which ends in the substantially closed duct and the outlet of which ends outside the closed duct for discharging into the environment.

Abstract: The invention relates to a method of feeding hatched chicks in a climate chamber during a first stage of life from hatching, the method comprising; a) controlling the temperature and humidity in the climate chamber, b) operating a ventilation means to generate an air flow through the climate chamber, and c) supplying the newly hatched chicks with live feed in the climate chamber.

Abstract: The invention relates to a tray (1) for containing a number of eggs (2) in an incubation chamber, the tray comprising a number of egg accommodation spaces (3) in which space an egg is able to be hatched, and at least one passage (4) 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.

Abstract: The invention relates to a method for producing chicken at a hatchery, the method comprising; incubating a batch of eggs in an incubating device during an incubating period of between about 7 to about 20 days, and then, for each egg of the batch, detecting the presence of a hatchable chicken embryo, based on the presence of a hatchable chicken embryo, dividing the batch of eggs into at least a hatchable batch portions and a not-hatchable batch portion, hatching the hatchable batch portion until hatching occurs, rearing of chicken hatched from said hatchable batch portion, wherein the method comprises at the hatchery processing the not-hatchable batch portion into feed and administering said feed at the hatchery to hatched chickens during rearing.

Abstract: A climate chamber for the treating of products with a conditioned gas stream includes a substantially closed compartment having two opposing lateral walls provided with one or more passages; a substantially closed channel which extends around the outside of the compartment and connects one of said lateral walls to the other of said lateral walls in order to form together with the compartment a substantially closed circuit; and a gas displacement device received in the substantially closed channel for circulating the conditioned gas stream through the circuit. The gas displacement device is provided with a reversing system configured for reversing repeatedly, in each case once a reversing time interval has elapsed, the direction in which the conditioned gas stream is circulated through the circuit. The gas stream passes through the compartment predominantly from one lateral wall to the other lateral wall.

Abstract: The invention relates to a method for brooding or growing poultry, wherein eggs of the first 3-5 layings of young animals, preferably hens younger than 29 weeks, usually starting from about 26 weeks, are collected and are hatched together, directly after hatching the hatched chicks are provided in crates with about 10-500 animals arranged in stacks in an incubator chamber, in which incubator chamber food and drinking are provided to each crate and the temperature, humidity, CO2 level and flow rate of air are controlled.

Abstract: A method and a compartment within an incubator, capable of allowing chicks to feed during the hatching process without reducing hatchability or livability. Thanks to immediate post hatch nutrition, the development during the chicks first days is significantly improved, resulting in a significant improvement in their weight as well. Furthermore, the accessibility of feed for the chicks is enabled and improved immediately after their hatching thanks to suitable lighting and the use of feeding troughs with transparent walls.
