In summer, laying hens are highly sensitive to heat, so it's essential to adjust their living conditions to ensure their health and productivity. First, reduce the stocking density. As temperatures rise, overcrowding can lead to stress and reduced egg production. When hens enter the summer season, aim for about 5 hens per square meter. Once the weather becomes more unstable, you can lower this to 4 hens per square meter.
Second, improve ventilation. When the temperature exceeds 25°C, open windows and install mesh screens to allow airflow. If the temperature goes above 30°C, consider setting up a shade structure over the chicken run. The structure should be as wide as the coop but slightly taller—around 50 cm higher than the roof of the henhouse—to provide better cooling.
Third, manage the water supply. Summer heat causes water in the drinkers to warm up quickly. Place coolers in shaded areas and change the water frequently. It’s also beneficial to let hens drink fresh well water, which helps lower their body temperature and keeps them more comfortable.
Fourth, adjust feeding times. In the early morning and late evening, when it's cooler, allow hens to access the outdoor area for their first feeding. After dark, bring them back inside to minimize time spent in the coop. During hotter periods, you can set up elevated platforms under the shade structure for them to rest overnight, helping them stay cooler.
Fifth, implement scientific feeding practices. With longer daylight hours in summer, increase the frequency of feedings. Aim to feed every 3–4 hours, offering larger portions in the morning and evening, and smaller amounts at noon. Adding two small feedings during each meal can stimulate appetite. Also, reduce the amount of corn and sorghum in the feed—keep corn below 45% and avoid sorghum altogether. Instead, increase the proportion of bran, fish meal, soybean cake, or peanut cake to support better nutrition and digestion.
Lastly, focus on disease prevention. Summer brings an increase in pests like mosquitoes and flies, which can spread diseases. Keep the coop clean by sweeping daily and adding fresh sand. After rain, remove any standing water from the run to prevent breeding. Ensure that hens have access to clean drinking water and regularly clean and disinfect feeders. Every two weeks, spray the coop with a 2% caustic soda solution to kill bacteria and mites. For more targeted treatment, mix 500 parts dichlorvos and spray into wall crevices. However, always move the hens out of the house before applying the spray. Additionally, mixing crushed garlic into their feed once every 3–5 days can help boost immunity and prevent illness.
