According to the different assembly forms, layer chicken cages are mainly divided into two types: stepped type (A type) and stacked type (H type). Type A layer chicken coop is the first chicken coop to be promoted in the transition from farmer's scattered farming to intensive chicken farming. Compared with the previous free-range mode, caged laying hens have greatly improved management efficiency and feeding density. Since then, the semi-A and H-type chicken cages have improved the arrangement of different layers of chicken cages, and further increased the breeding density to meet the increasing demand of large-scale and intensive breeding.
All new farms put into production this year use H-shaped chicken cages. The brooding chicken cage is generally 4-5 layers, while the laying chicken cage has 8 layers. Compared with the traditional half-A chicken cage, the H type can greatly increase the stocking density. The breeding density of the half-A three-layer chicken cage used by Yang's before is 12 chickens/square meter, while the H-type four-layer chicken cage can reach 34 chickens/square meter.
"At present, the main types of chicken cages used in farms are A and H cages. Semi-A cages have been gradually eliminated due to the inconvenience of manure removal. Newly built farms generally choose H cages." From the perspective of equipment cost investment , H-type chicken coops need to be equipped with automated equipment and closed chicken coops, so the cost is relatively high. The average hardware cost is about USD3-5 per layer per chicken, and the A-type chicken coop is USD1-3 per chicken. . However, from the perspective of later benefits, H-type chicken cages can not only improve land utilization, but also rely on automated management to reduce operating costs.
