How Many Eggs Do Swans Lay

The female lays up to seven eggs between late April and early May. Both sexes incubate the eggs, which hatch after 35-41 days. The young birds, or cygnets, sometimes ride on their parents’ backs and remain with the adult birds for four or five months. Cygnets are generally dingy brown above and whitish below.

Do swans lay eggs more than once a year?

So, that’s why swans tend to breed every year (provided they’re physically able to do so); the object being to produce as many cygnets as possible to increase the likelihood of their genes continuing to contribute to the gene pool of Cygnus olor.
