An array of vertically spaced rows of poultry cages are mounted on opposite sides of A-frame end supports with the uppermost rows engaging and secured to one another along a corner to provide additional stability to the frame. Load transferring hooks are coupled between vertically spaced cages to provide support for the inwardly projecting ends of the cages while the cages at opposite ends of the subassembly are mounted to the legs of the A-frame by brackets. Longitudinally formed struts extend and are coupled along the top edge of each row of cages for providing longitudinal strength to the cages while simultaneously compressively gripping a manure shield draped over a rear inclined surface of each of the cages. Improved integrally formed tab means are formed in a support bracket at the end of each row of cages for interlocking subassemblies in an installation. In some embodiments, improved doors are provided with outwardly projecting handles and U-shaped floor support hooks extend under the floor and attach to the forward wall of each of the cages. In other embodiments, improved feed tray holding clamps are employed with each cage to securely hold the feed tray in a predetermined relationship.
