a box having a bottom, sidewalls, a back wall, and a roof, wherein the box is configured to house hens and eggs;

an expulsion system that is configured to remove the hens from the box, wherein the expulsion system comprises:

a floor;

a first shaft provided with a gear wheel having a plurality of teeth, the gear wheel being fixedly connected with the first shaft;

a gear rack having a plurality of teeth that correspond to the teeth of the gear wheel; and a second shaft having an axis;

wherein the floor is both rotatably connected with the first shaft and pivotably connected with the box via the second shaft;

wherein the gear rack is both fixedly arranged in the box and 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 pivotably moving the floor by virtue of the first shaft moving along the path extending parallel to the gear rack and the second shaft pivoting around the axis.

2. The laying nest according to claim 1, wherein the floor is pivotably movable between first and second positions.

3. The laying nest according to claim 2, wherein the first and second positions are rotationally separated by up to approximately 100 degrees.

4. The laying nest according to claim 2, wherein one of the first and second positions is a substantially vertical position, and the floor is thereby configured to promote the removal by gravity of detritus from the floor.

5. The laying nest according to claim 1, wherein the first shaft is located between the back wall and the second shaft.

6. The laying nest according to claim 1, wherein the floor is rotatably connected to the first shaft by a plurality of supports.

7. The laying nest according to claim 1, wherein the floor is rotatably connected with the first shaft by a plurality of supports extending downwardly from the underside of the floor.

8. The laying nest according to claim 1, the box defining an opening configured to allow the eggs to roll out of the box and the floor being pivotably movable between a first position and a second position, wherein when the floor is moving toward the second position the floor is moving away from the opening.

9. The laying nest according to claim 1, wherein the floor is implemented as a wire mesh mat.
