What are the factors that affect the hatching period of poultry eggs?

The incubation period of poultry eggs is affected by many factors. The following is a detailed introduction of some main factors:

Temperature: Temperature is one of the most important factors affecting the hatching of poultry eggs. Different species of poultry have different requirements for incubation temperature. Generally speaking, deviations in incubation temperature will have an impact on the incubation period. Too high or too low temperatures may lead to abnormal incubation or a longer incubation period.

Humidity: Humidity also has an important impact on the incubation period. Proper humidity helps maintain the moisture balance within the eggshell and promotes normal development of the embryo. Insufficient or excessive humidity may affect the incubation period and the survival rate of the pups.

Ventilation: Good ventilation helps maintain gas exchange within the eggshell and maintain appropriate gas concentrations. Gas concentrations that are too high or too low may cause the incubation period to be prolonged.

Egg quality: Egg quality directly affects the incubation period. Affected factors include the integrity of the eggshell, whether the eggshell surface is contaminated, whether there are foreign objects in the egg, whether it is damaged, etc.

Incubation equipment: The incubation period is affected by the quality and performance of the incubation equipment. Equipment accuracy and stability are critical to the incubation period.

Egg transfer: During the incubation period, the appropriate time and method of egg transfer will have a certain impact on the incubation period and hatching rate.

Feed: The quality and type of feed for hens have a direct impact on egg quality and egg production rate, and further affect the length of the incubation period.

Condition of the hen: Factors such as the hen's weight, health, and age can also affect egg quality and egg production rate.

These factors directly or indirectly affect the incubation period and hatchability of eggs. Therefore, in order to obtain the expected hatchability, these influencing factors need to be comprehensively considered and regulated during the incubation period.
