There are four main characteristics of cage chickens:

1. The temperature difference between the upper and lower layers of the chicken cage. The solution to the temperature difference between the upper and lower layers of the chicken cage system is to install a diversion fan on the middle ceiling of the chicken house, which can control the temperature difference between each layer to 1 Within °C.

2. The problem of adequate oxygen supply to the flocks in the middle of the house. Providing oxygen supply in the middle of the house, the most effective measure is to adjust the wind speed of the air inlet and the uniform wind window. At the same time, it is necessary to avoid the danger of cold wind on cage chickens on both sides because of the wind speed problem. The most effective way to prevent this from happening is to use a baffle that allows the cold wind to fall into the aisle as it blows up, allowing the oxygen supplied to reach the middle cage.

3. Stable and balanced negative pressure ventilation is the key to the success or failure of cage chickens. It is also a key step in the middle cage to supply oxygen and prevent cold wind from entering the chickens on both sides. The role of negative pressure ventilation, one can ensure sufficient oxygen supply in the middle of the chicken house, the negative pressure determines the wind speed of the air inlet, the wind speed of the inlet wind determines whether the oxygen supply in the middle cage is sufficient; the second is to ensure the interior of the chicken house The air is fresh, and the negative pressure ventilation is the working principle of first discharging the dirty air in the chicken house and then pulling in the fresh air, so that the air in the chicken house is effectively circulated.

4. The three-dimensional cage will have a greater impact on the ventilation mode inside the house. For example, the distance between the cage and the cage, the density and weight of the flock, the width and length of the interior of the house, and the different breeds of the chickens will directly change the ventilation mode of the entire house. Even in a standardized house, the ventilation of each house will vary.
