Defenders of Wildlife is working to protect and strengthen the National Wildlife Refuge System, the only system of federal lands in the United States dedicated to wildlife conservation.
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).ertile chicken eggs can be stored up to 10 days (before incubating) with little loss in hatchability â as long as you keep them out of the refrigerator.
Start the incubator one or two days prior to setting the hatching eggs. Keep the temperature at 99 to 99.5 degrees Fahrenheit and humidity at 86% during the initial 25 days and then reduce temperature to 98.5 degrees Fahrenheit and increase the humidity to 94% for the next 3 days.
