ANATOMY

Detailed explanation-1: -Incubator temperature should be maintained between 99° and 100°F. The acceptable range is 97° to 102°F. High mortality is seen if the temperature drops below 96°F or rises above 103°F for a number of hours. If the temperature stays at either extreme for several days, the egg may not hatch.

Detailed explanation-2: -Make sure your incubator is set to the correct temperature. Forced air incubators should maintain a temperature of 99.5 – 100.5° F and still air incubators should hold a temperature of 100.5-101.5°F. The incubator should also have at least 60% humidity.

Detailed explanation-3: -On the last three days of the 21 days, when the hatching phase begins, the temperature should be lowered to around 36.9 degrees, while the humidity should be raised to around 70%.
