With the onset of spring, ducks almost immediately begin laying eggs.
In April and May, the duck lays only one egg every day. As soon as there are about 13 duck eggs, the bird simply sits on the nest, and the process of incubating the clutch begins.
For this reason, it is not uncommon to see a duck incubating, for example, twenty eggs or more.
A month later, little ducklings appear, which will become sexually mature after one year.
