How are layer cages used?

Layer cage It is a piece of equipment in high demand at poultry farms. Why is it necessary? Layer cage Why is that? In fact, it’s mainly due to large-scale farming. Layer cage It has facilitated management. So, how are layer cages used?

How are layer cages used?

1. Layer cage Poorly designed cage doors can easily cause chickens to escape and sustain injuries. Escapes occur when the door is not securely fastened and tends to loosen, while injuries result from protruding steel tips on the door itself. When these loose steel tips are long, they can readily pierce the skin of a chicken’s neck, leading to external wounds or even cervical dislocation. Whether it’s a pull‑out door or a corner‑type door, there should be no exposed steel ends when the door is not in use. If such ends must remain, their length should not exceed 1 cm. If you’ve purchased a defective chicken cage, you can either trim off any unnecessary steel protrusions or bend them into a loop.

2. Chicken cage frames are typically fabricated by welding angle steel or stamping steel plates. Regardless of the fabrication method, they must be robust and capable of withstanding pressure. If the cage is unstable, it may collapse, damaging the housing, waterers, and feeders, which can trigger severe stress in the birds and reduce egg production. This issue is more likely to occur when welds are weak or when the angle steel used is hard, brittle, or excessively thin. Once assembled, the upper and lower tiers should maintain an appropriate spacing; specifically, the gap between the top mesh of the lower tier and the bottom mesh of the lower tier must be at least 4 cm to prevent chickens from becoming trapped in this space and dying. The top mesh of a properly installed laying cage should remain level, without tilting forward or backward. At the intersection of the frame’s diagonal beams and the cage’s bottom mesh, a horizontal support bracket should be welded to bear the weight of the cage and its contents, ensuring that the feeder does not carry the load of the cage and the birds. The bottom mesh of the lower-tier cages must be positioned at least 25 cm above the ground; otherwise, it could impede manual manure removal.

What are the common technical specifications of layer cages?

1. Each cage measures 40 cm in length, 45 cm in depth, with a front height of 45 cm and a rear height of 38 cm. The cage floor is sloped at an angle of 6–8 degrees and shaped as a concave trough to collect eggs. If the slope exceeds 10 degrees, the eggs may be damaged by impact as they roll out; if the slope is less than 7 degrees, the eggs will not roll out easily. The egg-collection chute extends 12–16 cm beyond the cage. The front opening is 21–24 cm wide and 40 cm high, with the bottom edge approximately 4.5 cm above the cage floor. The mesh openings on the cage floor are 2.2 cm apart, with weft spacing of 6 cm. The mesh dimensions of the top, side, and back panels vary considerably: typically, the warp spacing ranges from 10 to 20 cm, while the weft spacing is 2.5 to 3 cm.

2. Each cage can house 3–4 chickens. Common configurations include tiered, semi-tiered, and overlapping designs. Hang waterers and feeders at height, ensuring a clearance of 5–6 cm between the egg‑catching board and the floor mesh to provide an escape gap. Feeders should be mounted high, about 2 cm above the chickens’ backs. Laying hens are typically housed in three‑tiered, fully tiered (or stacked) systems.
