Incubation Times in the Modern Hatchery

The chicken embryo generally needs 21 days (504 h) to complete incubation, including the drying of down (Etches, 1996). In practice however, incubation periods vary considerably, as observed by Laughlin (2007) in large scale field surveys, which recorded pulling times from the setting of eggs of 500 up to 526 hours .This variation can partly

To Candle or not to Candle, that’s the Question…

During the incubation process, eggs are candled to determine the number of infertile eggs and eggs with dead embryos, together indicated as ‘clears’. This can be done as early as day 5 - 6 of incubation by an individual candling light, but it is time consuming and the risk of candling errors (e.g. accidentally removal

Finding Optimum Incubation Temperature

When a hatchery manager talks about incubation temperature, he or she refers to the temperature set point at the controller of the incubator. This temperature set point regulates the temperature of the air stream along the incubator’s temperature sensors. If the air temperature is too high or too low, the incubator controller adjusts the cooling
