A poultry nesting system has a nest house with an adjacent platform raised above the surface of the surrounding substrate. The platform has an upper surface and at least a portion of a perimeter of the platform comprises a wire mesh covering a space between the substrate and the upper surface. The wire mesh is formed by a plurality of strands including an upper strand and a lower strand. At least a portion of the upper surface of the platform is supported by a plurality of platform floor supports positioned on a perimeter of the platform. Each of the plurality of platform floor supports includes a bracing member, an upper cap on an upper end of the bracing member and a lower cap on a lower end of the bracing member. The upper cap has an attachment mechanism on an upper portion thereof configured to interact with the upper surface to lock the platform floor support to the upper surface of the platform such that the platform floor support supports the upper surface in its raised position above the substrate. The upper cap has an upper catch configured to interact with the wire mesh and hold the wire mesh in place, wherein the he upper catch forms an upward-facing valley for receiving the upper strand. The lower cap has a lower catch configured to interact with the wire mesh and hold the wire mesh in place, wherein the lower catch forms a downward-facing arch for receiving the lower strand. A length of a travel space under the downward-facing arch of the lower catch is greater that a length of a travel space in the upward-facing valley of the upper catch.L'invention concerne un système de nidification de volaille qui comprend un logement de nid avec une plate-forme adjacente surélevée au-dessus de la surface du substrat environnant. La plate-forme a une surface supérieure et au moins une partie d'un périmètre de la plate-forme comprend un treillis métallique recouvrant un espace entre le substrat et la surface supérieure. Le treillis métallique est formé par une plural
