Raising pullets is a delicate balancing act. These young birds require a controlled environment that encourages rapid growth while preventing stress and injury. Unlike standard cages, a high-quality rearing system must adapt as the bird grows—from a day-old chick to a ready-to-lay pullet.
A pullet that reaches sexual maturity with the correct body weight and bone density will have a longer peak laying period and lower mortality. Modern rearing systems focus on:
Uniformity: Ensuring all birds in the house grow at the same rate.
Training: Teaching young birds how to use automated feeding, drinking, and manure systems so they aren’t stressed when moved to layer cages.
Bio-security: Protecting the vulnerable immune systems of young chicks through touchless automation.
Big Herdsman (Qingdao Big Herdsman Machinery Co., LTD) has established itself as a global leader in “Smart Rearing” solutions. Their pullet rearing cages are designed to be “Simple, Reliable, Green, and Efficient,” catering to the specific physiological needs of developing birds.
Big Herdsman’s pullet cages are engineered with versatility in mind. As the chicks grow, the equipment adapts:
Adjustable

Big Herdsman Drinking system
Lines: Using 360° nipple drinkers that can be raised or lowered to match the height of the pullets, ensuring easy access to water at every stage.
Variable Feeding Windows: The feed troughs are designed with adjustable openings to prevent smaller chicks from getting stuck while ensuring older pullets can feed comfortably without waste.
Specialized Floor Mesh: The bottom net uses a high-density, small-grid design to protect the tender feet of day-old chicks, preventing injury while allowing manure to pass through to the cleaning belts efficiently.
Young pullets are highly sensitive to temperature fluctuations. Big Herdsman integrates their BH9100PRO controllers to manage the “micro-climate” within the rearing house.
Precision Heating: Coordinating with high-efficiency fans and air inlets to eliminate cold drafts.
Automated Lighting: Mimicking natural day/night cycles to stimulate healthy hormonal development without causing precocity (laying too early).
A standout example of Big Herdsman’s capability is their recent pullet project in Thailand. To combat extreme humidity and heat, Big Herdsman delivered an 8-building, 4-floor brooding cage system.
By customizing the ventilation layout and using high-durability, hot-dip galvanized steel (275g/m²), they ensured that the equipment could withstand corrosive tropical environments while maintaining a 99% uniformity rate across the flock.
What makes the Big Herdsman system a strategic choice for 2026 is its transfer compatibility. Because the feeding and drinking logic in the rearing cages mirrors their BH600/BH625 layer systems, the pullets experience zero “transfer shock.” This results in a faster start to the laying cycle and higher overall ROI.
