An aviary is provided having a floor and a first aviary cage including a first outside surface enclosing a first inside area. The aviary further comprises a second aviary cage substantially similar to the first aviary cage and including a second outside surface enclosing a second inside area. The second aviary cage is positioned at a height from the floor greater than a height from the floor at which the first aviary cage is positioned. An aisle extends between the first aviary cage and the second aviary cage. A first perch extends from the first outside surface of the first aviary cage and into the aisle at a first vertical distance from the floor. A second perch extends from the second outside surface of the second aviary cage and into the aisle at a second vertical distance from the floor. The first and second vertical distances from the floor are not equal.

The invention relates to a poultry housing unit, in particular for ducks to lay eggs, a poultry house, in particular for keeping ducks, and a method for keeping ducks. The invention relates to a poultry housing unit for ducks to lay eggs, comprising a plurality of nests arranged one beside the other and above a floor area, at least one supporting element extending in the vertical direction from a lower supporting end to an upper free end and arranged relatively movably in the vertical direction in relation to the floor area, and a locking element which interacts with the supporting element to block movement of the supporting element in a vertically upward supporting direction relative to the floor area and to allow movement of the supporting element relative to the floor area in a vertically downward direction of free motion.

An aviary that includes a system for providing litter to birds and for circulating the litter throughout the aviary. A litter distribution chain extends through at least some of the scratching platforms. The litter distribution chain receives litter from a storage container and then transfers the litter through the aviary for use by the birds on the scratching platforms. At least a portion of the litter from one scratching platform is directed to move to a scratching platform on a lower level where the litter may be used by birds occupying this lower level. This circulation pattern repeats on the current level, with the recycled litter being deposited on at least one scratching platform near the next lower aviary tower level. Once the litter reaches the lowest aviary tower level, it remains there until it is removed from the aviary by a belt or other means.

Disclosed is a system (100) for a poultry farm. The system (100) includes an automated guided vehicle (110). The automated guided vehicle (110) includes a body (111) adapted to mount a plurality of devices (170), a plurality of wheels (112), a plurality of sensors (113), a collection bin (114) at the rear end (116) of the automated guided vehicle (110), and a detachable protection arrangement (160) at a front (115) of the body (111). The system (100) also includes an overhead power railing unit (120), an open overhead utility line (130) with a vertical water supply line (140) with a pump (142), and a vertical conveyor (150) to retrieve the litter, eggs or wastewater from the collection bin (114) and dispose in the open overhead utility line (130).

Methods and systems of promoting fertilization of eggs of an avian. While inseminating a plurality of avian eggs a spectrum substantially concentrated within a narrow range of wavelength irradiates the plurality of inseminated avian eggs to increase the motility of the sperm to increase the probability of conception of avian from the inseminated eggs.
