Incubation

INCUBATORS

There are different types of incubators. Our values are referring to a model with air circulation fans.


EGG STORAGE

Depending on the length of the storage, there are different methods that increases hatchability.
For longer storage periods (>7 days), the eggs should be stored with the small end up, as this increases the hatchability. For short term storage, the small end down storing position is preferable.
The storage temperature should be between 10-13°C (50-55.4°F ).
Before putting the eggs into the incubator, they should be slowly brought to a temperature of 21°C (69.8°F). This should happen over a course of two days.


With increasing storage time, the hatchability decreases.

INCUBATION (28 days)

Day 1-25:    37,6°C (99.7°F) and 50% humidity
Tag 26-28:  37,3°C (99.15°F) and 65% humidity

To determine the optimal temperature, we recommend the usage of an infrared thermometer. The shell temperature should be measured on the side of the egg.


EGG TURNING

Turning the eggs in a frequent way, is mandatory to get the best results. In nature, a hen turns their eggs about 96 times a day. If your incubator doesn’t support such a high turning frequency, you should still use the highest available option.
Low turning frequencies are related to early embryo deaths and malformations.
Also the turning angle is of importance. The angle should be >45 degrees.

Two days before the poults hatch, the turning of the eggs should be stopped. The poults must bring themselves in the perfect hatching position.


EGG CANDLING:

On day 7. and 21. eggs should be „candled“. Eggs that are not developing should be removed from the incubator, to avoid the risk of infections.

HATCHING

If you’ve done everything correctly, you’ll be rewarded. 🙂
