Spring is the golden season for incubating chickens, and it is also a good season for chickens. Poultry hatching should be based on the development of the embryos, strictly controlling temperature, humidity, ventilation, cold and egg turnover.
1. Temperature: Incubation room and incubation room temperature are kept at about 25°C; egg surface temperature is kept at about 39°C before hatching; 37.5-38°C should be kept at late hatching; the hatcher temperature is generally controlled between 36-37°C. It is appropriate.
2. Humidity: Keep the indoor relative humidity at 60%-65%; the relative humidity of the incubator is 55%-60%; the relative humidity of the hatcher is 65%-70%.
3, turn the egg: In order to make all parts of the egg evenly heated, to maintain the normal development of the embryo, should turn the egg on time. Turn the eggs by hand, turn the eggs every 4 hours, turn the eggs automatically, and turn them once every 30 minutes. The angle of turning eggs is 45-90 degrees.
4, cool eggs: 12-13 days after hatching, eggs should be cool twice a day, so that the eggs within the heat generated by the embryo in a timely manner to prevent the death of "self-ignition". The temperature of cool egg should be controlled at about 36°C, that is, when it comes into contact with human skin, it can be warm and not cool.
5. Ventilation: While maintaining normal temperature and humidity, it is necessary to pay attention to frequent ventilation, and the room air in the indoor or incubator is often kept fresh.
