(1) Suitable temperature for laying hens breeding equipment: The temperature for laying hens is 35-33 ℃ for 1-2 days and 33-32 ℃ for 3-7 days. From now on, it will decrease by approximately 2-3 ℃ per week until it reaches approximately 21-18 ℃ for 5-6 weeks of age. The suitability of the supplied temperature should not only be observed by observing the thermometer, but also by observing the behavioral state of the chicks. For example, when the temperature is normal, the chicks are mentally active, have a good appetite, drink moderate water, sleep quietly, and have a comfortable sleeping posture, mostly in a prone position. The chicks are evenly distributed throughout the breeding house; When the temperature is high, chicks stay away from heat sources, spread their wings, stretch their necks and open their mouths to breathe, drink frequently, and have poor appetite; When the temperature is low, the chicks are dense and close to the heat source as much as possible, crowded and clumped, trembling, making waves of cold "naqing" sounds, and their appetite decreases. Chickens are sensitive to warmth and cold, so special attention should be paid to preventing temperature fluctuations and making every effort to maintain a balanced temperature. When controlling the temperature, the temperature should be higher at night or on rainy and snowy days; During the day, when chickens are active and the weather is warm, the temperature should be lower; The temperature of weak chicks should be higher, while that of healthy chicks can be lower.

　　(2) Suitable humidity for laying hens breeding equipment: humidity is closely related to the evaporation of water in the chicken body, heat dissipation, and cleanliness of the chicken coop.

　　① When the temperature is high and the humidity is low, excessive water loss in the rooster can easily lead to dehydration of the chicks. In addition, due to dryness, dust can fly in the house, which can easily lead to respiratory diseases.

　　② When the temperature is low and the humidity is high, the inside of the house is both cold and humid, and the chicks are prone to catching a cold, causing wet bedding, leading to gastrointestinal diseases and coccidiosis.

　　③ When the temperature is high and the humidity is high, the heat in the chick's body is difficult to dissipate normally, causing stuffiness, decreased appetite, slow growth, and weakened resistance. Normally,

　　The chicken coop should be kept dry to prevent bacterial reproduction and infection, but the relative humidity should not be lower than 40%. Suitable relative humidity: 60% -65% before 10 days old, and 50% -60% after 10 days old. When the humidity is insufficient, water can be sprayed on the corridors, floors, surrounding walls, or flues inside the house, or a water basin can be placed on a heat source to evaporate water vapor to increase the humidity inside the house; When the humidity is too high, a moisture-proof layer can be laid on the ground of the chicken coop, the temperature inside the coop can be appropriately increased, ventilation and ventilation can be strengthened, and the bedding material in the flat chicken coop can be frequently changed. Wet feces and bedding inside the coop can be removed in a timely manner to prevent water leakage from the water dispenser, etc.
