In the combination of an enclosure for raising chickens or the like, said enclosure having a floor and litter on said floor, said litter including a plurality of discrete units distributed over said floor and of a depth to substantially prevent direct physical contact between any chicken in said enclosure and said floor, each of said units being of a foamed polymer coated with a polymeric material, said polymeric coating material having the physical characteristics of (1) remaining pliable at ambient temperatures, (2) being bonded to said foamed polymer with such strength that it will not separate from said foamed polymer upon impact after being dropped several feet, (3) being bonded to said foamed polymer with such strength that it will not separate from said foamed polymer by walking, pecking or scratching by chickens, (4) sloughing chicken droppings to thereby cause said droppings to move to the floor rather than remain on the surface of the litter, (5) being impervious to air and water, and (6) being chemically non-reactive with chicken droppings.
