Ducks are gregarious and aggressive. The duck's good gregariousness is established by fighting, which is the pecking order. The males and females have their own superior relations, forming their own independent pecking order: the strong ones give priority to feeding, drinking water and mating, occupying the highest position in the flock, and undertaking the responsibilities of fighting the invaders, defending the group, mediating and limiting the attacking behaviors within the flock, while the weak ones are ranked behind in turn,

Each member has its own location. In the case of fixed duck group members, the established hierarchical relationship has been maintained. This structure ensures the peaceful coexistence of the duck population and promotes the high yield of the duck population.
