Common Types of Broiler Breeder Cages and Their Characteristics

The one-stage brooding cage is widely used in areas where laying hens are raised under a two-stage system. Its key feature is that chickens can be reared from one week of age right up to the onset of egg production—around 100 weeks of age—thereby reducing the stress associated with flock transfers and improving labor efficiency. Broiler breeder cage The structure has three levels; during the chick-rearing phase, only the central level is used, and as the chickens grow, they are gradually distributed to the upper and lower levels. Each square meter can accommodate 25 growing chickens.

Egg‑laying chicken cages: At present, the egg‑laying cages manufactured in China mainly comprise lightweight cages for white‑shelled hens and medium‑ to small‑sized cages for brown‑shelled layers. In addition, a small number of extra‑heavy‑duty cages are used in breeding farms for parent stock.

The above are several commonly used types in poultry farms. Broiler breeder cage In addition, the design of chicken coops—tailored to different breeds—facilitates management and promotes the health and well-being of the flock. Special attention should also be given to stocking density and regular disinfection and sanitation practices.

Broiler breeder cage It is a key piece of equipment in modern large-scale poultry farming; however, chicken cages made from different raw materials can vary significantly in their performance, directly impacting farm profitability. For instance, the service life of the machinery, the quality of fresh eggs, and the egg breakage rate are all influenced by the cage’s material composition.

The main reason is that if the chicken coop’s raw materials are prone to rusting, the high humidity inside the coop will accelerate corrosion, significantly shortening the structure’s service life. Moreover, rust on the coop can contaminate the eggshells, compromising their appearance. On the other hand, if the galvanized wire used in the coop has insufficient elasticity, it may further increase the rate of cracked eggs.

Broiler breeder cage The key raw materials include cold‑sprayed zinc, hot‑dip galvanizing, electrostatic powder coating, alloy wire, and several others.

Cold‑spray zinc, also known as phosphating, produces a thin zinc coating that begins to rust after 2–3 years and typically lasts 6–7 years—making it the lowest‑quality option among all materials. Hot‑dip galvanizing, or hot‑dip zinc coating, yields a thick zinc layer that resists corrosion and offers exceptional durability, with a service life of 15–20 years. However, its main drawback is uneven zinc deposition in the hot‑dip bath, which often results in sharp burrs—this remains a significant challenge in the industry—and can easily be scraped off by a feather duster or puncture raw eggs placed inside the cage, leading to a high rate of egg breakage. Electrostatic powder coating, also called electrostatic powder spraying, uses powdered paint that adheres to the cage surface via the attraction of high‑voltage static electricity. This process creates a highly corrosion‑resistant phosphating film between the equipment cage and the coating, firmly bonding the paint to the cage’s exterior so it does not flake off—even when bent 360 degrees. Moreover, it remains impervious to strong alkaline environments, ensuring robust durability and a service life of 15–20 years. Thanks to the high‑voltage electrostatic adhesion, the finished surface is smooth, aesthetically pleasing, and free of burrs.
