By allowing hens to lay on their eggs - it will slow down their egg production. Therefore, it is necessary to utilize incubators to hatch fertile eggs. Still Air Incubators, also known as Thermal Incubators, heat eggs using no air movement methods. When incubating quail eggs in a Still Air Incubator, maintain a temperature of 103 degrees. The temperature should be decreased to 100 degrees during the last 1-2 days of incubation.
Humidity is also necessary for a successful hatch.
However, humidity is difficult to measure in a Still Air Incubator. It is recommended that a flat water pan covering the incubator floor be used to provide humidity. During the last couple of days of incubation sprinkle eggs with water to increase humidity slightly. Some examples of these incubators are shown on this page. Forced Air Incubators maintain a constant temperature throughout the incubator by means of a circulation fan.
