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.

An egg processing apparatus is provided. Such an apparatus includes a plurality of egg processing devices configured to interact with an avian egg. A sanitization system is in fluid communication with the egg processing devices. The sanitization system is configured to deliver sanitizing fluid to the egg processing devices for sanitization thereof after interaction with an egg. The sanitization system has a valve-less manifold assembly. An associated method is also provided.

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 transfer system is provided. Such an egg transfer system includes a controller configured to receive a classification signal indicative of an egg classification status for each of a plurality of eggs carried by a flat. A transfer head assembly is in communication with the controller and is configured to remove a plurality of eggs from the flat. The eggs are grouped into at least a first and second subset based on the egg classification status. The controller is configured to direct the transfer head assembly to selectively release the first and second subsets separately based on the respective egg classification status of the eggs. An associated method is also provided.

The present disclosure relates to a system configured to inject objects, such as eggs, with a fluid, wherein said objects each comprise at least two object parts, such as embryo tissue, embryotic or allantoic fluid and an air pocket, of which at least one object part is to be injected, by advancing injection needles to a determined depth, which depth is expected to correspond with the at least one object part to be injected, into the objects and injecting fluid into the objects at the determined injection depth. The system a sensor to monitor pressure or flow of the fluid during injecting, and to generate a monitoring signal, the control being configured to detect an operational state of the needles and/or the fluid, indicating proper operation or defect in the system, such as a blocked fluid line and/or needle, based on the monitoring signal representing the monitored pressure or flow.

A controller for controlling illumination emitted by lighting elements within an environment comprising animals and a respective filter between each of animal and the lighting elements, the controller configured to: control the lighting elements to emit illumination having a first spectral composition for a first time period to produce, on a first side of the filter, a first level of illumination as experienced by a visual system of the animals; control the lighting elements to emit illumination having a second, different spectral composition for a second, subsequent time period to produce, on the first side of the filter, a second, different level of illumination as experienced by the visual system of the animals; and control the lighting elements to emit illumination throughout the first and second time periods to maintain, on a second side of the filter, a minimum level of illumination as experienced by a visual system of the animals.
