The hatching chicks in the spring need to pay attention

Spring is the golden season for hatchling chickens, and it is also a period of good sales for chickens. When hatching chickens should be based on the development of the embryo, strict control of temperature, humidity, ventilation, turning eggs and cool eggs off.
First, the relative humidity in the humidity-maintaining room is 60%-65%; the relative humidity of the incubator is 55%-60%; the relative humidity of the hatcher is 65%-70%.
Second, the temperature incubation room, incubation room temperature maintained at about 25 °C; egg surface temperature in the early incubation period at about 39 °C; incubation period should be maintained at 37.5-38 °C; hatcher temperature is generally controlled between 36-37 °C should.
Third, turn the egg in order to make the eggs evenly heated parts, to maintain the normal development of the embryo, should turn eggs on time. When the fire pit hatches, the eggs can be turned once every 4 hours. The machine is hatched and turned every 2 hours. The angle of turning eggs is 90 degrees.
Four, cool eggs hatch 12-13 days later, cool eggs should be regularly 2 times a day, so that the heat generated by the fetus inside the eggs in time to be distributed to prevent "natural" death. The temperature of cool egg should be controlled at about 36°C, that is, when it is connected with human skin, it can be warm and not cool.
V. Ventilation While maintaining normal temperature and humidity, it is necessary to pay attention to frequent ventilation, so that the air in the indoor or incubator can always be kept fresh.
