Pre-incubation to improve hatchability

Even under optimal ?conditions, beyond one week of storage the hatchability of eggs will drop 0.5 – 1.5% per day with the percentage increasing as storage extends further. After two weeks of storage, the chick quality will also be impaired. Pre-incubation is one tool to reduce the negative effects of long egg storage. Pre-Incubation will not and cannot improve hatchability, but helps to maintain it over longer periods of time (see Figure 1 below). Therefore it starts making sense using
