temperature and humidity for egg incubation
Perhaps the most important parameter is temperature â chicken eggs should be incubated at a temperature between 99 and 102 degrees Fahrenheit (99.5 is often considered to be ideal) and 50 to 65 percent relative humidity (60 percent is often considered the ideal).onsider that number to be a target â not an absolute. During the final three days of incubation, the eggs should ideally be located in a slightly cooler (98.5 degrees) and more humid (65 percent relative humidity or greater) environment to facilitate successful hatching.
This is important since the air stratifies in these incubators. There can be as much as a 5Â° difference in temperature from the top to the bottom of some of the still-air incubators. Humidity should be 60-65% (80-90Â° wet bulb) during incubation and 70-75% (92-97Â° wet bulb) at hatching time.It is very easy to overheat the eggs in still-air incubators and difficult to maintain proper humidity.his is important since the air stratifies in these incubators.
