Spring is the golden season for hatchling chickens, and it is also a season for chickens. The author proposes that the following technical points should be mastered according to the development of the embryo when hatching. The relative humidity in the room is maintained at 60% to 65%; the relative humidity of the incubator is 55% to 60%; the relative humidity of the hatcher is 65% to 70%. Turning eggs in order to heat evenly all parts of the egg and maintain the normal development of the embryo should turn the egg on time. When the fireball hatches, the egg can be turned once every 4 hours; the machine is hatched and turned once every 2 hours, and the angle of turning eggs is 90 degrees. After cool eggs are incubated for 12 to 13 days, eggs should be cooled twice a day, so that the heat generated by the fetus in the eggs can be emitted in time to prevent “self-ignition†from being killed. 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. Ventilation While maintaining normal temperature and humidity, it is necessary to pay attention to frequent ventilation to keep the air in the room or incubator fresh.
