It is better to keep the temperature within 18~23°C and the lowest temperature should not be less than 15°C. In case of windy weather, the tarpaulin should be shaken (according to changes in the outside temperature, half or all of it should be shaken) to prevent the temperature inside the home from suddenly falling. Every day, the size of the air inlet is adjusted according to the weather conditions and the performance of the flock. The air inlet should be fixed with iron wire or rope firmly to the plastic cloth and plywood, so that the wind blowing upward, do not let the cold wind directly blow chickens, to prevent cold stress caused chicken disease. Do not open the windscreen at the temperature controller to prevent the cold air from blowing directly on the temperature controller. The exhaust fan cannot be opened and it is easy to cause air pollution in the house. When installing the timed temperature control exhaust fan, select the louvers to be complete. Do not select the north-facing exhaust fan. Before the winter, clean up the dust from the heater, and make the louver parallel when the heater is first opened, so that the hot air can fill the shed evenly. Do not open the door of the workshop and the door of the chicken house at the same time to prevent cold air from blowing directly into the house. Observe the chickens carefully every day. If the chicken is on the scaffold and the back hair is erected, it means the house is too cold. To adjust the air intake, block the air leakage, to prevent stress, so as to avoid the onset of colds in chickens. Watch the weather forecast every day and prevent it in advance.
Ventilation in the autumn and winter seasons is better with fresh air and slower air flow. Before winter, repair the area that should not enter the wind, especially the exhaust air at the exhaust fan must be handled well to prevent the chickens from being affected due to the partial cold air, the poor ventilation of the house and the low temperature near the exhaust fan. And it affects production. When the smell of ammonia in the house is large, the temperature in the house should be increased first, and then the ventilation volume should be increased. When the air in the house is relatively dirty in the morning, if it is necessary to increase the amount of ventilation, it should be gradually increased, preferably at a high temperature at noon. Each ventilation time can be shorter and ventilation times can be more. Never leave dead corners when ventilating. If you want to increase the number of fans to open, carefully observe the performance of the flock after the increase, and proceed without any adverse reactions.
Humidity should be added before winter. Winter litter is relatively dry, and it is often sprayed or spray-disinfected. If there is water under the scaffolding, the water under the scaffolding will be released in the autumn when the temperature is high, and then sprinkled with white ash. When the room temperature is appropriate, increase the ventilation. Adjust the nipple drinking line water pressure to less than 10 cm, or adjust the water level of the drinking fountain to less than 1 cm. Always check the drinking line. Nipple joints with leaking water in the water dispenser should be replaced or repaired immediately. If the water leakage in the drinking fountains is to be dealt with promptly, it will prevent the ammonia smell in the chicken house from being excessive due to water leakage and affect the health of the chickens.
