Abstract
Cage structure for poultry and the like comprises a number of cage rows mounted on A-frames in pyramided, stepped back, A-shaped, elevational array. Each cage row includes a bottom/back member and a top/front member joined together to form a row of cages of rectangular cross section. Each cage row is tipped forward to incline the cage bottom so as to urge eggs laid in the cages to roll forward into an egg collecting trough at the cage front. The bottom element of the bottom/back member forms at least a portion of the top of the cage row next below. A feeder trough forms a portion of each cage front.
