The orientation of henhouse is related to environmental effects such as lighting, heat preservation and ventilation. Orientation should be determined according to the local geographical location and climatic conditions. Appropriate orientation should meet the requirements of chicken for light, temperature and ventilation. The winter and spring monsoon in the north is mostly northwest wind, and the chicken house is better to the south.
2. Interval
Reasonable coop spacing is the condition of epidemic prevention and isolation of chickens, which can reduce the mutual infection between coops. The distance between henhouses is too small, which will affect the ventilation and lighting effect of henhouses. Considering the above factors comprehensively, the distance between henhouses should be 3 ~ 5 times the height of eaves, which can meet the requirements of lighting, ventilation and epidemic prevention. If the distance is too large, it will occupy too much land, waste land, increase investment in infrastructure such as roads and pipelines, and make management inconvenient. If the distance is too small, it will increase the interference between henhouses, which is not conducive to the lighting, ventilation and epidemic prevention of henhouses.
3. The height of the henhouse
It depends on the feeding method, the size of the henhouse and the climatic conditions. In general, the clear height of a henhouse (the distance from the ground to the eaves or ceiling) is 2 ~ 2.4m In hot areas, it can be increased to about 2.5m Increasing the height of the henhouse can strengthen the ventilation of the henhouse and reduce the influence of high temperature. In cold areas, reducing the height of henhouse is beneficial to heat preservation. Considering the convenience of people's access and management, the height of the henhouse should not be less than 2m.
4. Number and area of henhouses
According to the area of the stocking site, the size of the chicken and the feeding density. Generally, the distance between henhouses is 15 ~ 20m, and each henhouse can accommodate 300 ~ 500 chicks or 200 ~ 300 adult chickens. When the ground is generally flat, the feeding density of chicks, medium-sized chickens and laying hens is 20-30 per square meter for 0-3 weeks, 4-9 weeks 10- 15 per square meter, and 8 10-20 per square meter after 20 weeks. If the number of henhouses is small, or the henhouses are too close or connected together, it is easy to cause chickens to concentrate in a range for food, which will lead to overgrazing, damage vegetation, affect the growth of chickens and make them vulnerable. Illness.
5. Roofing form of henhouse
There are many forms of chicken house roofs, including single slope, double slope, asymmetric double slope, arch, flat roof, bell tower and half bell tower. Generally, double slope type is adopted, and single slope type can also be adopted according to local climate and environment. Single-slope henhouses are generally small in span and suitable for small-scale chicken farms; Double-slope henhouse has a large span and is suitable for large-scale chicken farms. In the dry and hot areas in the south, the roof can be raised and ventilated. The height of chicken coop can be reduced in the cold area in the north, which is beneficial to heat preservation.
The above is an introduction to the relevant experience on how to scientifically and rationally lay out chicken coops, hoping to help everyone.
