A manure shield is provided for multi-tier poultry cages, and the like, wherein the lower tiers of cages have an exposed area positioned directly below the adjacent upper cage tier. The shield comprises a substantially continuous, rigid support panel, having its lower edge attached to the uppermost edge of one of the lower cage tiers, and extends upwardly and laterally therefrom at an acute angle to a position adjacent the bottom of the upper cage tier. A sheet of flexible, substantially imperforate material is positioned over the upper side of the support panel to prevent manure droppings from entering the lower tier of cages. The flexible sheet is mounted over the support panel, such that vibrations and other movements in the cages are transmitted by the support panel to the flexible sheet, whereby manure droppings stuck to the flexible sheet are disjoined therefrom by the vibrations, and in turn slide off of the shield into a collection pit.
