This invention relates to laying nest having a rack drive expulsion system. As disclosed herein, the invention preferably comprises a laying nest for hens comprising a box and a rack drive floor expulsion system. The floor pivotably moves between first and second positions by virtue of a gear rack that is fixedly connected to and disposed within the box, and a gear wheel that is rotatably connected to the floor. Accordingly, the expulsion system provides for the selected removal of hens from the laying nests as desired.

A poultry management system having at least one animal holding area with a holding area floor for a poultry animal occupying the animal holding area and a conveyor comprising a conveyor belt having an upper track and a lower track disposed below the upper track. The lower track is disposed adjacent to the animal holding area and is adapted to receive one or more eggs deposited by the poultry animal occupying the animal holding area and transfer the one or more eggs for further processing.

A poultry-farming battery cage farming has at least two horizontal cage rows, formed with cage enclosures, arranged alongside one another, that are formed with double cages made up of cages that back on to one another. Under each row extends a droppings receptacle, over which air-fanning flaps are longitudinally spaced apart, each air-fanning flap having an upper force-transmission part and a lower fan part mounted on a transverse axis arranged near an upper air-fanning-flap end. The two cages of each double cage have cage bottoms extending away from one another transversely and are separated from one another by a common vertical longitudinal rear wall arranged at a vertical spacing above the upper air-flap end. The fan part of the air-fanning flap is arranged under the associated cage bottoms. The air-fanning-flap end is arranged in a double-cage area, from which the cage bottoms extend away from one another transversely.

A barn-type poultry farming system comprising, on a supporting frame, at least one multistorey battery of farming cages. At one side of the multistorey battery there is an inspection corridor and at another side there is a free area on which the poultry can walk and for transit to cages of different farming levels, the cages being open and provided with perches on the side directed toward the free area.

A poultry holding system that can be erected tool-free by assembling lengthwise and crosswise members on support posts. Multiple upright support posts are set up in an evenly spaced grid. The crosswise members and lengthwise members are constructed as U-profile rails, with through-holes in the horizontal sections of the U-profiles that allow the members to be assembled and supported on the support posts. The poultry holding system thus constructed can have at least two tiers, one above the other. The assembly components are designed to be particularly economical, which allows greater flexibility in the design and construction of the poultry holding system to accommodate the constraints of the particular facility.

An excrement-drying device (1) for animal stalls, such as poultry stalls, comprises an excrement conveyor belt (2) for conveying the excrement along a conveying direction (F), wherein the excrement conveyor belt (2) extends over a conveying length (L) and has a top side (10) for receiving the excrement (K), and a drying unit (3) with at least one discharge element (4), which has at least one air nozzle (5) for blowing air onto the excrement (K) lying on the excrement conveyor belt (2) in order to dry the excrement (K). The top side (10) for receiving the excrement (K) of the excrement conveyor belt (2) is divided into several excrement conveyor belt sections (TB1, TB2) arranged one after the other in the conveying direction (F); and the at least one discharge element (4) is arranged in such a way that air is blown onto only one of said excrement conveyor belt sections (TB1, TB2).

A bird nest box system is provided including a housing defining a nesting enclosure, a movable nest floor, and a floor movement mechanism. The nesting enclosure has a front opening and an egg outlet at a back of the nesting enclosure. The nest floor is mounted within the nesting enclosure and over the floor movement mechanism. The floor movement mechanism includes a driveshaft and at least one floor actuation member coupled to the driveshaft and rotatable by the driveshaft to move the nest floor. From a lowered floor position, initial rotation of the driveshaft in a first direction moves at least one of the at least one floor actuation member to tilt the nest floor toward the egg outlet. Continued rotation of the driveshaft moves the at least one floor actuation member to rotate the nest floor toward the front opening and to a raised floor position.
