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

Managing Incubation Temperature to Combat Increased Early Mortality

As a breeder flock ages, the number of ‘clear’ (infertile) eggs increases as a result of decreased fertility and increased early mortality. Consequently, with higher numbers of clear eggs, a higher proportion of the heat produced by developing embryos in the fertile eggs is absorbed by the ‘cold’ clear eggs placed around them. Embryonic temperature

How Hatchery Management changes when starting Single-stage Incubation

Management in a multi-stage hatchery is based on a daily routine of setting eggs according to a strict setting schedule per setter type. The common principle for establishing a setting schedule in a multi-stage incubator is based on the need to transfer metabolic heat from more developed embryos to the less developed, heat-demanding embryos in
