1. Reduce stocking time. When the winter is cold, try to reduce the time of stocking. In general, the activity will take place in a plastic greenhouse. When the weather is warm, it can be stocked after 9 a.m. and recalled at around 3 pm.
2. Reasonable feeding. The winter days are short and long nights, and additional feeds should be added at night, or they should be fed once before turning off the lights.
3. Fill light. Due to the short natural lighting time in winter, artificial light should be added to 16 hours. Normally, light is supplemented twice in the morning and evening, fixed at 5 o'clock in the morning and filled to dawn, and at 5 o'clock in the evening, it is filled to 9 o'clock.
4. Insulation and ventilation combined. In winter, the weather is cold and temperatures drop. At low temperature, the virus survives for a long time, and the resistance of chickens decreases under cold stress. In addition, the chicken house needs heat insulation. Breeders often close the vents, which results in a decrease in the air quality in the house and long-term hypoxia and hypothermia. In the harsh environment with high humidity, high ammonia, and high carbon dioxide, the resistance of chickens is reduced, resulting in a high incidence of respiratory diseases. Therefore, more ventilation work should be done at the same time.
5. Collect eggs in time. In winter, the outside temperature is low. If eggs are not collected in time, they will often crack. At this time, you need to increase the number of quail eggs and do not put the eggs in the egg nest overnight.
