The temperature of drinking water in young chickens must not be lower than 18-20 °C, and the suitable water temperature range should be 18-22 °C. Young laying hens can effectively promote their vitality after drinking hot water. Test results have shown that for 1-119 days of chicks, the survival rate of drinking water is 6.7% higher than that of drinking cold water, and the daily weight of 119-day-old chicken is increased by 97 grams. The average daily weight gain is 0.8 grams, and every 1 kg of body weight is added. Feed consumption is reduced by 0.7 kg. Broiler chickens had a net increase of 10.5%. After drinking hot water, the retention rate and live weight of chickens entering the house can be increased, and the amount of feed consumed by each egg can be reduced. The test results showed that the egg production rate of the chickens increased by 5.4% after drinking hot water; the live weight increased by 187 grams at 64 weeks and the average egg production increased by 4.2 pieces, and the feed consumption per 10 eggs decreased by 0.08 kg.
