1. Chick cages: cages are used to raise chicks, generally 3 to 4 layers of overlapping cages are used. The total height of the cage is about 1.7 meters, the height of the cage frame feet is 10-15 cm, the length of each single cage is 70-100 cm, the height of the cage is 30-40 cm, and the depth of the cage is 40-50 cm. The mesh holes are generally rectangular or square, the bottom mesh diameter is 1.25 cm x 1.25 cm, and the side mesh and top mesh diameters are 2.5X2.5 cm. The cage door is set at the front, the cage door gap can be adjusted from 2 to 3 cm, and each cage can hold about 30 chicks.
2. Broiler chicken cages: the combined form is mostly three-layer overlapping type, with an overall width of 1.6-1.7 meters and a height of 1.7-1.8 meters. The single cage is 80 cm long, 40 cm high and 42 cm deep. The mesh at the bottom of the cage is 4 cm × 2 cm, and the remaining meshes are 2.5 cm × 2.5 cm. The cage door size is 14 cm × 15 cm, and each single cage can accommodate 7 to 15 chickens.
3. Breeding chicken cages: the common combination forms are ladder, half ladder and overlap. Each single cage is 40 cm long, 45 cm deep, 45 cm high at the front, 38 cm high at the rear, and has a slope of 6°-8° at the bottom of the cage. The egg trap that protrudes outside the cage is 12 to 16 cm. The cage door is opened in front, 21 to 24 cm wide; 40 cm high, with a gap of about 4.5 cm left from the bottom net. The cage bottom mesh has an aperture spacing of 2.2 cm and a weft spacing of 6 cm. The aperture range of the top, side and back nets varies greatly. Generally, the meshes have a warp spacing of 10-20 cm and a weft spacing of 2.5-3 cm. Each single cage can raise 3 to 4 chickens.
