Hatchability is the most important elements for producing more ducks. Hatchability is an indicator used to determine the economic value for any commercial hatchery. Optimal conditions during the incubation process may be defined as those leading to maximum hatchability of healthy ducklings. One of the main factors in the success of the duck hatching process is to adjust the appropriate temperature and humidity with the ventilation of the eggs enough as well as a proper turning of the eggs. In addition, the complete disinfection of eggs and incubator machine, and the process of egg candling to define the fertile eggs in order to maintain the hygienic conditions of the incubator and ensure a high hatchability. By knowing the simple steps of hatching duck eggs, successful management can access different ways to improve the hatchability. Therefore, this review was conducted to reveal the incubation factors that influence the hatchability of duck eggs and also the new ways to improve the hatchability.
