Cobb-Vantress has developed the hatcher management programs as a reference for the ideal time, temperature, ventilation, and humidity conditions for a proper incubation process.

THE HATCH WINDOW
The hatch window is the time frame spanning from the first chick to the last chick hatching.
Chicks hatching too late can cause:
- poor quality chicks,
- increased pipped eggs, and
- live embryo unhatched eggs.
- higher incubation temperatures increase metabolism and promote increased embryonic development and
- lower temperatures reduce metabolism and delay embryonic development.
For optimal hatch and chick quality, it is critical to maintain a uniform temperature and humidity across the hatcher.
In addition to chick temperature, the eggshells in the hatcher basket can be used to indicate if adjustments are needed to the time and temperature of chicks in the hatcher.
