First, feed feed. According to the different weeks of age of chickens, daily feed consumption per chicken is arranged: 10 grams for 1 week old, 18 grams for 2 weeks old, 26 grams for 3 weeks old, 50 grams for 4 weeks old, 60 grams for chickens about. Second, breeding methods. The best condition is mechanized hatching, which is suitable for large and medium-sized chicken farms. General farmers can use a small incubator or electric incubator; it can also be used to control the temperature of the electric cooker on top of the fire, put a hot water bottle, and then cover the quilt, the temperature is maintained at 3.8 degrees Celsius. Third, temperature, humidity, light control. Temperature control is the first stage of raising black-bone chickens. Due to their small size, poor living ability, poor body temperature regulation, and especially high mortality during brooding, the important reason is that improper control of temperature and improper breeding of chicks into chicks The initial temperature is 32 degrees Celsius, and gradually decreases by about 2 degrees every week. After 6 weeks of age, the room temperature is reduced to about 20 degrees and can be maintained at a constant temperature thereafter. Controlling humidity is the second level. Early hatching of chicks due to hatching water loss, should be appropriate to increase the humidity of the chicken house, generally 1 week of age is 65%, 2-6 weeks from 60% gradually decreased to 55%. The humidity inside the house is too large, and a small amount of crushed lime can be put under the thick bedding to absorb water; the doors and windows can also be opened to promote moisture evaporation and gas exchange. Adjusting the lighting is the third level. During the brooding process, appropriate lighting may be added at night. The length of the light is closely related to the age at which chicks reach sexual maturity. It is best to use 24 hours of continuous light in the breeder's 2 days after hatching, which will benefit the chicks to eat, drink and exercise. From day 3 onwards, daylight is reduced and daylight is available after 14 days of age. Light from the 20-week-old period of the black-bone chicken began to increase, 0.5 hours per week, at the peak of egg production (30-31 weeks old), 15-16 hours of light, and 17 hours of appropriate light at the end of the laying period.
