1 The proportion of male and female male and female breeders is generally 1:1 to 1:15 for light chickens, 1:10 to 1:12 for medium chickens, and 1:8 to 1:10 for heavy chickens. 2 Store eggs properly 2.1 Shorten the shelf life. The hatching period of the general breeding eggs does not exceed 7 days before hatching. In the optimum storage environment, the hatching rate of the breeding eggs begins to decrease after 7 days. 2.2 During the storage of eggs, cover them with plastic film to prevent the eggs from dehydration during storage. Using this method can improve the hatching rate of 1.3% to 3.0%. 2.3 Temperature and humidity during the storage period of eggs. The temperature within a week of storage is 16°C to 17°C, and preferably 10°C to 12°C over a week. The relative humidity is generally maintained at 75% to 80% to prevent the moisture in the eggs from evaporating. 2.4 When the eggs are stored, the egg heads up and stays upright. In the incubator, it should be head down to obtain a higher hatching rate. 3 Grasp the seven steps of the incubation period 3.1 On the 15th day after the eggs are hatched, place an airtight film on the shell to reduce the air-permeable area of ​​the shell by 13%. This will increase the hatching rate and hatch the chicks. It is well developed and grows quickly. 3.2 Spray. During hatching, spraying with ordinary clean water 4 times a week, the hatching rate of fertilized eggs can be increased by 7.3% to 25%. 3.3 Use anion generator. The slight negative ionization of air in the incubator has a positive effect on hatching quality and hatchability. In the incubator with an air ion concentration of 150,000 to 300,000 ions per square centimeter, the hatching rate can be increased by 6.5% to 11.4%. 3.4 Before hatching the eggs, the red and infrared lasers with a radiation flux density of 1000 watts per square meter are irradiated for 40 milliseconds. The hatching rate can be increased by 16.3%, and the robust chicks increased by 3.64%. 3.5 Lighting at hatching can speed up hatching without increasing malformation and mortality. Light hatching shortened the incubation time by 36 to 48 hours. Light- hatched chicks had large physique and obvious weight gain effects. The opening age was 5 days earlier. 3.6 Temperature during the incubation period. The general temperature of 37 °C ~ 39.5 °C, the temperature is too high or too low, will shorten or extend the incubation period, so that embryonic mortality increased. 3.7 Controlling the temperature is the key to successful incubation. The exact method for determining the optimum temperature during hatching is to periodically weigh the same hatching egg sample within 1 to 18 days after the start of hatching. The hatching egg should lose about 0.7% of the weight on a daily basis. Humidity in principle grasp the two high, the middle low, 1 to 7 days of incubation humidity of 60% to 65%, 10 to 18 days of 50% to 55%, 19 to 21 days of 57% to 60%. 4 Correct midwifery chicks are generally shelled out in 20-22 days, but some chicks are unable to break shells. Therefore, hatching midwifery is generally performed before the 22nd day of hatching, but if the allantoic blood vessels are not dry, they should be put immediately. Return to the incubator and wait for it to dry before assisting in shelling.
