德州众信孵化机孵化过程中湿度的控制（Dezhou Zhongxin humidity control incubator during incubation） Control of humidity during incubation No matter what poultry eggs hatch with incubator, there is a certain degree of control on humidity. Take eggs as an example. The chicken eggs have a wide range of adaptation to humidity. But it does not mean that we should not pay attention to humidity. If we want to improve the hatching rate, I can only say that humidity and temperature should be taken into account. During the incubation period of the requirement for the humidity of 1~7 days is approximately 60%, with the increase of days, humidity will also have the corresponding changes in 8~16 day humidity was 50%~55%, 18 days later, with the gradual forming of the chicken, the relative temperature should also be increased, usually 65~70%. The newborn chicken weight, because varieties, seasons, incubation conditions do not differ greatly, the majority in 682%, ranging from 60 to 75%. The influence of high humidity and low on hatching process When the temperature is too high, it hinders the evaporation and elimination of the chicken egg wrapped liquid, which causes the big belly of chickens, the chicken body tissue and the yolk contain too much moisture, and the body appears to be bulky and dull. Humidity is too low, is caused by excess water evaporation, eggs, lean chicken, muscle plump, feathers too compact, small size. Therefore, it is also necessary to master proper humidity. As we all know, temperature and temperature are directly related to the hatching rate during incubation. Therefore, the temperature and humidity control of large incubators are described in detail: Based on the selection of different poultry embryo development, the incubation equipment temperature was analyzed in different periods: 1. The temperature condition during incubation: the incubation period is 21 days. 1~6 days is 38.5 degrees; 7~14 days is 37.5; 15 days is 38; 16~21 days is 38 ~ 38.5 degrees centigrade. 2. Temp
