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).uring 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.
  99.5 degrees Fahrenheit (37.5 degrees Celsius) is optimum incubating temp. for duck eggs with the temp. being lowered by one degree to 98.5 in the last 3 days of incubat â¦ ion (25-28th day). Lowest temp.- highest temp. range is 97 - 102. 99.5 degrees Fahrenheit (37.5 degrees Celsius) is optimum incubating temp. for duck eggs with the temp. being lowered by one degree to 98.5 in the last 3 days of incubat â¦ ion (25-28th day).
