In winter, the northern region experiences a significant drop in humidity and temperature, with frequent north winds. This period marks a crucial time for chicken feeding and management. Chicken farms must pay close attention to several key aspects of poultry health care to ensure optimal conditions for their flocks.
First, preparation is essential. Before winter arrives, a thorough inspection and maintenance of the chicken house should be conducted. Seal any cracks in the walls, replace broken windows, and prepare materials like plastic film and straw curtains for insulation. For semi-open houses, remove any pergolas and properly cover the plastic. Heating equipment should also be checked and installed correctly. Farms using coal-fired boilers or fire broilers must inspect flue pipes and chimneys regularly, repairing or replacing them if leaks are found. Large-scale operations should stock up on common antibiotics, disinfectants, and green or blue succulent feed to support the flock’s health.
Second, adjusting the feed formula is important. The large temperature differences between day and night in winter increase energy consumption. To compensate, the energy level of the feed should be increased by 5% to 10%. Adding 1–2% animal fat can also help. If possible, adding brown sugar to drinking water may improve egg production. Laying hens that have been through a long laying period and summer heat may need more protein to maintain egg production and support molting. Vitamin C (200 mg/kg) or baking soda (0.10–0.15%) can be added to enhance eggshell quality. Carrots or green radishes can also be included for additional vitamins. Chop radishes just before use to maximize their benefits.
Third, grouping chickens appropriately helps manage the flock efficiently. Remove low-yield hens and thin young chickens. Separate moulting hens into new groups, focusing on those with bright red combs, wide pubic bones, and soft abdomens. When regrouping, avoid creating too many small groups, as this can lead to fighting. Keep group sizes around 100–200 birds, monitor closely, and isolate aggressive or injured birds to prevent further issues.
Fourth, proper lighting is essential for maintaining egg production. Provide supplemental light twice daily: once in the early morning and once in the evening. Ensure total daily lighting reaches 16 hours, even during cloudy or snowy days. Consistent lighting helps maintain the egg-laying cycle.
Fifth, daily management requires careful attention. Monitor weather forecasts and prepare for cold snaps. Chickens are sensitive to stress, so all activities—feeding, watering, collecting eggs, and cleaning—should be done calmly and consistently. Avoid sudden changes, such as feed replacements, which can cause stress. Broiler chickens should be brought indoors at night when temperatures drop, and layer chickens can be fed at night to encourage eating before lights out.
Sixth, environmental hygiene is critical. Winter is a peak season for respiratory diseases, so regular disinfection of the chicken house, equipment, and water sources is necessary. Use 0.5% spirit sprays weekly, and apply lime paint or caustic soda for external areas. Disinfect tools like feeders and drinkers with bacterin or strong disinfectant solutions. Clean and disinfect vehicles and cleaning equipment regularly.
Seventh, prevent gas poisoning by keeping the chicken house clean. Ammonia buildup from feces and damp litter can be harmful. Use dry, absorbent bedding like wood shavings, and maintain a thickness of over 5 cm. Minimize watering to prevent wet litter, and use ammonia-absorbing agents like ferrous sulfate or hydrated lime to keep air quality safe.
Eighth, vaccination is vital for disease prevention. Follow a strict immunization schedule, ensuring all chickens are properly vaccinated. Common vaccines include those for avian cholera, infectious bronchitis, Newcastle disease, and others. Alongside vaccination, add preventive medications like oxytetracycline or sulfa drugs to the feed to support immunity.
Ninth, monitor feces closely. Changes in color, consistency, or smell can indicate illness. White, pasty, or sticky droppings may signal coccidiosis or other infections. Green or bloody stools could point to more serious conditions. Early detection helps prevent the spread of disease.
Tenth, isolate sick chickens promptly. Observe each bird daily for signs of illness, such as lethargy, poor appetite, or abnormal breathing. If an infection is suspected, isolate the affected chicken immediately and thoroughly disinfect the area. Regular checks and prompt action can save the entire flock from major outbreaks.
