At what temperature must eggs be held during incubation?
The incubation temperature requirements for most hatching eggs is surprisingly uniform. The eggs of almost all domestic bird species (and many wild species) are incubated at the same incubation temperature. Therefore, eggs of several different bird species can be incubated at the same time within the same incubator. The incubation temperature of naturally (nest) incubated eggs is controlled by the hen. The recommended temperature within an artificial incubator depends upon the type of incubator being used. If the incubator used has a fan for air circulation (forced air), the temperature must be adjusted to 99-100oF. An incubator without an air circulation system requires a higher temperature. The temperature in this “still-air” incubator is measured using a thermometer with the bulb positioned at the same level as the top of the incubating eggs. The recommended temperature in this type incubator is 102oF. The reason for different temperatures is that circulating air warms all points ar
