1 Temperature: Chicken eggs should be incubated at a temperature between 99 and 102 degrees Fahrenheit (99.5 is often considered to be ideal). 2  Avoid temperatures outside the 97â103 Â°F (36â39 Â°C). 3  range. 4  If the temperature remains beyond either extreme for several days, hatchability may be severely reduced.
To maximize the shelf life of eggs, do not store them in the molded egg rack of the refrigerator door, as the temperature is too warm - the eggs will last much longer when they are stored in the main body of the refrigerator, in their purchased carton. How long can raw eggs be left at room temperature? Bacteria grow rapidly at temperatures between 40Â°F and 140 Â°F; raw eggs should be discarded if left out for more than 2 hours at room temperature. To further extend the shelf life of eggs, freeze them; do not freeze eggs in their shells.
