Poultry coops.-A coop is fitted with removable flooring formed with longitudinal ways in which slide the lower edges of a. run, which telescopes within the coop. The coop 1 may be made from a single piece of sheet metal bent at the rear corners A and bent again at B to form a span roof, the edges being folded together at the ridge and secured by bolts. A stiffening wire 3 is rolled in the front edge and extends across the open bottom, being bent to form stops 4 which hold the loose floor 6 in place. The floor is bent downwardly at the sides and has outwardly turned flanges, which rest on corresponding flanges on the walls of the coop, and form longitudinal grooves in which slide the lower edges 9 of the rim 8. The end of the rim closes the coop when not extended, and is provided with adjustable ventilators 15 and doors 12, 13 covering the outlet 11. In a modification, the wire 3 is dispensed with, the gable of the coop being strengthened by a perforated triangular plate, the top of the rim being then flat. In this form, the floor carries near its front edge outwardly projecting strips which grip the lower edge of the walls of the coop. A sliding door may replacÚ the doors 12, 13.
