Abstract
Flooring for raising poultry and particularly broiler birds comprises a subfloor in the form of a grid formed by strips at right angles defining openings therebetween of the order of four inches across which will support the foot of a person but provides the openings for passage of waste material therethrough. An upper floor on top of the subfloor is formed of a molded grate or perforated flexible plastic sheet which is supported above the subfloor by vertical flexible pegs which are pressed into openings in the subfloor and are integral with the molded plastics floor. The pegs are resilient so that on compression by the foot of a person walking on the upper floor, the pegs compress completely so that the person walks effectively on the sub floor. The birds tend to sit between the pegs rather than on the pegs and thus flexible flooring cushions around them.
