The front net not only involves the feeding, the cage door of the layer chicken cage, the convenience of catching the chicken and the chicken running, but also affects the height of the chicken cage group.
1. Height, generally speaking, the front net height refers to the front height of the chicken coop, which is mainly determined by the shape of the chicken. On the front line, it is necessary to arrange the egg gap, the egg plate, the trough and the cage door, and some need a sink. The gap between the eggs can be 55 to 65 mm. In order to prevent the chicken head from sticking into the egg trough and quail eggs, the gap between the eggs should not be too large. The installation position of the trough is generally considered to be the best with the upper edge of the inner edge and the chicken back, so it is generally taken as 18. A 220 mm, otherwise, difficulty getting in and out of the chicken. Therefore, the front height should be 380-420 mm. The specific size should be determined according to the feeding method. The layer county should take a large value, but considering the convenience of feeding and management, the total height of the stack should not exceed 1.7 meters.
2. The type of the front net, the structure of the front net is many, and the three typical structural types are shown in the figure. They have their own advantages and disadvantages: (a) more materials; (b) the use of materials, but it is not convenient to catch chicken; and easy to run chicken; (c) has the advantages of the first two, it is worth promoting.
3. Grid, the front net is the feeding surface, the grid spacing is determined by the chicken neck, generally 50-60 mm is suitable. Because the chicken neck is often in motion, it is easy to cause deformation and cause the chicken to run. For this reason, the front net should use a relatively thick steel wire, and the upper and lower ends should be arranged with two horizontal steel wires as much as possible to prevent the joints from being desoldered and causing the chicken to run.
4. The eggshell plate and the eggshell plate have the functions of protecting the egg and blocking the feces. For the full-step cage, it can also be used to overlap the upper and lower layers of the chicken cage to reduce the size of the chicken battery cage. The shape and size of the layer cage eggshells vary widely from place to place. Generally, the width is about 70 mm and it is installed at an angle of 45. We think that the shape is simple and the size is not to hinder the feeding and activities of the chicken.
