A shade apparatus for use in broiler poultry houses can include a plurality of contoured vanes positioned in vertical alignment. Each vane can have first and second opposed lateral sides and is contoured upwardly such that the first lateral side resides below the second lateral side. The vanes are connected by a first plurality of spacers attached to the vanes proximate the first lateral side of the vanes, and a second plurality of spacers attached to the vanes proximate the second lateral side of the vanes. A portion of each vane extends over a horizontal axis defined by the first lateral side of a vane positioned immediately above. The apparatus can include brackets that facilitate mounting of the apparatus over a fan vent of a broiler poultry house and maintain the vanes a predetermined optimal distance from the fan vent.
