(under subclass 329) Subject matter wherein significance is attributed to the structure of the nest upon which the fowl rests.
(1) Note. This subclass does not include a patent for a nest wherein the sides are continuous with the nest bottom and no distinct bottom can be discerned (e.g., semispherical in shape).
(2) Note. This subclass provides for nest bottom structure which is more than simple fibers or particulate matter.
(3) Note. The disclosed nest bottom generally serves some specific purpose such as cushioning the egg, providing comfort to the fowl, facilitating cleaning, or disinfecting the nest.
