Abstract
A laying nest is provided with an improved ejection system, in which the risk of expelling eggs together with the hens is suppressed. The floor of the laying nest can rotate in both directions. Thanks to this arrangement, at first it can be rotated in a first direction for inclining it towards the egg collection area and ensuring that all the laid eggs are removed; next, it can be rotated in a second, opposite direction for inclining it towards the hen coop and thus expelling the hens from the laying nest. In a preferred embodiment, the driving arrangement of the ejection system of the laying nest is entirely arranged below the floor of the laying nest, so as to not occupy room in the laying nest and to be protected from manures and dirt that may be present in the laying nest.
Claims8
A laying nest, comprising:
- a floor, a roof, and side walls including a first side wall, comprising an entry opening, and a second side wall, opposite to the first side wall and comprising a discharge opening,
- wherein the floor is a platform,
- wherein the platform is rotatable about a first rotation axis which is parallel to the first side wall and adjacent to the first side wall, and the platform is rotatable about a second rotation axis which is parallel to the second side wall and adjacent to the second side wall,
- wherein the laying nest has a driving arrangement for rotating the platform about the first rotation axis and the second rotation axis, and
- wherein the driving arrangement comprises a rotation shaft, arranged below the floor, substantially at a middle position, which rotation shaft is rotatable in both opposite directions, and a rocker, which is integral to the rotation shaft and comprises two diametrically opposed arms which are arranged for coming into contact with and exerting a pressure onto a first side of the platform which is adjacent to the first side wall and onto a second side of the platform which is adjacent to the second side wall, respectively.
