Abstract
A disposable laminated tray liner for use by poultry breeders and growers is formed by affixing an expanded paper layer to a planar paper base. The layers are adhered by a waterproof adhesive or the like and the irregular top surface of the expanded paper layer provides traction for turkey poults or chicks while assisting in keeping the birds clean and healthy.
