Abstract:

A poultry flooring system, comprising a housing structure having four walls and a floor; a substantially inelastic film member raised above the floor to provide a raised floor structure. The inelastic film member comprises apertures to permit waste products and ventilation to pass through the inelastic film member; wherein the inelastic film structure is maintained under tension to reduce need for independent support structures between the film member and the floor. In a preferred embodiment, an air bag system or other mechanical support system is used to reduce sag in the inelastic film supported under tension, whereby the inelastic film may be easily raised and lowered during use and harvest.
