Incubating Eggs Of Different Sizes

It’s All About Incubator Design

Carla van der Pol MSc.

Embryo development and chick quality are optimal when the embryo temperature is maintained between 99.5 – 100.5ºF throughout incubation. When eggs are not incubated at an embryo temperature between 99.5 – 100.5ºF, embryo development is impeded and chick quality at hatch and in later life is negatively affected. Egg shell temperature (EST) is a reflection of the embryo’s temperature and can therefore be used in practice to determine the correct machine temperature required for a batch of eggs.
