This article delves into how modern layer farms can achieve efficient operations and sustainable development through scientific cage system design. It focuses on the advantages of the H - shaped structure in space utilization, automated feeding, egg collection, and manure cleaning. Combined with Q235 steel and environmental coating processes, the durability of the equipment is ensured, and strict compliance with ISO9001, ISO14001, and CE standards guarantees compliant production. Meanwhile, ventilation and temperature control optimization schemes and selection strategies for farms of different scales are shared to help farmers reduce labor costs, improve egg production rates, and build a healthy and high - yielding modern chicken farm.
