A laying nest comprising boxes ( 12 ) having at least a bottom ( 24 ), sidewalls ( 18 ), a back wall ( 22 ), and a roof ( 20 ). Further, the laying nest comprises an expulsion system which comprises a shaft ( 26 ) which is provided with at least one gear wheel which is fixedly connected with the shaft. An expulsion plate of the expulsion system is rotatably connected with the shaft and via a support shaft is pivotably and slidably connected with the box. The expulsion system further comprises a gear rack ( 34 ) which is fixedly arranged in the box and which is configured for cooperation with the gear wheel, such that upon rotation of the shaft, this shaft moves along the gear rack, thereby carrying along the expulsion plate.
1. A laying nest for hens comprising:
at least one box having at least a bottom, sidewalls, a back wall, and a roof, wherein the at least one box is configured to house hens and eggs;
an expulsion system that is configured to remove the hens from the at least one box, wherein the expulsion system comprises
at least a first shaft provided with at least one gear wheel having teeth which is fixedly connected with the first shaft;
at least one expulsion plate which is rotatably connected with the first shaft and which via a second shaft is pivotably and slidably connected with the box;
at least one gear rack having teeth that correspond to the teeth of the gear wheel, wherein the gear rack is fixedly arranged in the box and which is configured for cooperation with said gear wheel, wherein upon rotation of the first shaft, the first shaft moves along a path extending parallel to the gear rack, thereby carrying along the expulsion plate thereby moving a lower edge of the expulsion plate closely along the bottom by virtue of the first shaft moving along the path extending parallel to the gear rack and the second shaft sliding vertically along a linear path relative to the box.
2. The laying nest according to claim 1 , wherein the gear rack extends along a curved path.
3. The laying nest according to claim 2 , wherein the expulsion plate is implemented as a wire mesh mat.
4. The laying nest according to any one of the preceding claims, wherein the second shaft is slidably and rotatably received in a slot which is provided in a sidewall associated with the second shaft.
