To check the incubator thermometer, place the bulb next to the bulb of a clinical the oral kind used to check body temperature or a laboratory thermometer. Hold under lukewarm tap water and compare the readings. NOTE: This is a popular science project and quite accurate, but not recommended for breeders, as any significant temperature change the egg is exposed to is likely to hurt the developing chick.

Ensure that the incubator is placed in a stable environment. Ideally, incubators should be placed in a room where the temperature remains in the 70s. However, most incubators including the Mini Advance can work with temperature variations from 60 - 80 degrees Fahrenheit. Hatchability may still occur at temperatures as low as 60 or as high as 90 degrees. March 16, at pm.
