Abstract: A flooring unit for an animal enclosure such as a chicken coop or pen is disclosed. The unit is of relatively thin and flat rectangular shape overall and was a planar tread surface, two transverse elongate mounting members at respectively opposite ends and two longitudinal engagement members at respectively opposite sides of the unit moulding. A grid-like area is provided between the members and includes openings through which waste material can pass. The mounting members are designed to receive fastening elements such as screws for securing the unit to an underlying support. Also, they may be of L-shape in cross-section and are complementary to one another so that two similar floor units may be positioned end-to-end with respective, complementary mounting members fitted together. Fastening elements can then be driven through both mounting members and into the support. The engagement members are designed to engage a respective, corresponding engagement member of an adjacent moulding.
