This article explores how effective ventilation and temperature control in layer hen houses directly impact egg-laying performance. It explains the science behind H-type cage ventilation systems—featuring side-wall intake and top exhaust airflow—to maintain stable temperature and humidity, preventing heat stress that reduces egg output. Real-world case studies show measurable improvements in productivity after system upgrades. The durability of aluminum-zinc alloy coatings is also highlighted for long-term corrosion resistance in harsh farm environments. Practical tips on monitoring temperature, humidity, and routine maintenance help farmers manage chicken house conditions confidently. Supported by industry data and visual airflow diagrams, this guide delivers actionable insights for improved flock health and profitability.
