How to build a scientifically sound and reasonable chicken house for laying hens
AbstractVentilation design: When building a chicken house, windows need to be designed and protected with wire mesh; if it is a windowless chicken house, a ventilation fan needs to be installed. Disinfection pool: A disinfection pool can be set up at the entrance of the chicken house, the floor inside the house needs to be higher than the outside, and a drainage ditch can be designed around the chicken house. Cold protection and heat protection: The thickness of the bricks on the north wall needs to be increased, and a ceiling should be installed on the roof. Lighting for the chicken house: Build the chicken house in a south-facing north position or install artificial lighting equipment. Chicken house roof: Use single-slope and double-slope roofs.
1. Ventilation design
1. When building a chicken house, ventilation must be considered in advance, because chickens have a relatively fast metabolism, and during this process, their demand for gases is relatively large, so the harmful gases they expel are also relatively numerous.
2. Therefore, the ventilation conditions of the chicken house must be good. Windows can be designed in the chicken house, mainly to facilitate ventilation. If the chicken house has windows, attention must be paid to protection. Wire mesh can be used for protection to prevent birds and animals from entering the chicken house, thereby reducing the spread of disease.
3. If it is a windowless chicken house, a ventilation fan needs to be installed, which is beneficial for the flock to absorb fresh air and also helps expel harmful gases.
2. Disinfection pool
1. The chicken house needs to be regularly disinfected and sterilized in daily management, which is beneficial for preventing and controlling various diseases and thus ensuring the healthy growth of the flock.
2. Generally, sterilization and disinfection require water, so it is necessary to facilitate the discharge of sewage formed by mixing water and debris from the chicken house. Therefore, the inside of the chicken house needs to be higher than the outside, about 0.2-0.3m higher is sufficient, and then a drainage ditch can be designed around the chicken house, and a disinfection pool can also be set up at the entrance of the chicken house.
3. Good heat preservation and heat protection
1. When building a chicken house, cold protection and warmth preservation as well as heat protection and cooling must be considered. The suitable growth temperature for chickens is about 10-23°C.
2. In winter, if the temperature is below 5°C, the feed intake of chickens will increase, thereby reducing feed utilization. In summer, higher temperatures will affect the normal growth of chickens. Therefore, a ceiling needs to be installed on the roof of the chicken house, and the thickness of the bricks on the north wall should be increased.
4. Lighting for the chicken house
1. When building a chicken house, natural light must be used or artificial lighting equipment must be installed. Reasonable lighting is beneficial for heat preservation, sterilization and disinfection, thereby promoting chicken growth.
2. A south-facing north chicken house is more conducive to lighting. In winter, the sunlight angle is more slanted, allowing more light to be obtained. In summer, the sunlight angle is more direct, which can reduce direct sunlight.
5. Chicken house roof
The roof of the chicken house must be well designed. A ceiling can be set up and filled with rice husks, which helps with heat insulation. The roof can generally use single-slope and double-slope roofs, and its edges need to focus on streamlined design, which is beneficial for rainwater to flow down smoothly and can also provide shade.
