The Type A tiered chicken cage features a distinctive “A”-shaped, multi-level arrangement. This design incorporates a scientifically engineered staggered, stepped configuration that creates natural ventilation channels between each tier. Such an offset layout not only enhances air circulation and reduces ammonia concentrations within the poultry house but also provides breeders with unobstructed viewing angles, facilitating timely detection of abnormalities during routine inspections. This cage type is particularly well-suited for medium- to large-scale commercial operations, especially in subtropical or temperate regions where high ventilation and air exchange are critical for modern poultry houses, delivering more than a 30% improvement in ventilation efficiency compared with conventional floor-rearing systems.

　　Two structural options are available for the cage system: the monolithic welded design, constructed from high-strength galvanized steel and formed in a single operation using precision CNC equipment, offers exceptional structural stability and long service life, making it ideal for long-term, fixed-use poultry farming applications; the modular assembly design, based on a standardized, component-based approach with standardized interfaces for connecting individual parts, facilitates easy transportation and installation while allowing flexible adjustment of the number of tiers and inter-tier spacing to match the specific dimensions of the chicken house, making it particularly well suited for brooder houses or breeder farms that require frequent layout modifications. Both designs undergo anti-corrosion treatment to ensure compatibility with the varying temperature and humidity conditions across different regions.

　　Compared with conventional H‑type cage systems, A‑type cages offer significant advantages in operational space design. Their unique stepped layout provides a 40–60 cm-wide access aisle in front of each tier, complemented by a height‑adjustable feeding platform. This configuration not only facilitates precise procedures such as vaccination and individual health checks but also ensures ample space for equipment maintenance. In emergency situations, the open design enables rapid isolation of affected birds, while malfunctions in the manure‑removal system can be addressed directly from the side, resulting in approximately a 40% improvement in maintenance efficiency compared with H‑type cages.

　　In terms of automated configuration, the Type A tiered chicken house can be seamlessly integrated with modern poultry farming equipment systems. The automatic feeding system employs a combination of screw conveyors and overhead trolley feeders, ensuring feed distribution uniformity of over 98% across all levels; the drinking water system is equipped with an intelligent water-pressure regulator that automatically adjusts the water outlet height based on the chickens’ age; the egg-collection system utilizes a soft conveyor belt paired with a central egg-collection tray, effectively reducing the egg-breakage rate; and the manure-removal system features either a tracked or scraper-type design, coupled with a timed automatic control unit, enabling scheduled cleaning 2–3 times per day. The integrated application of these automated systems increases the operational efficiency of a single poultry house by 2–3 times compared with traditional methods, fully meeting the production requirements of modern intensive farming.
