Swans lay between 1 and 10 eggs. Younger pens tend to lay more. The pair will build their nest and when the eggs are laid the pen will incubate them with her brood patch until they hatch. She will leave her nest only occasionally for a quick wash and does not eat during this period.
When the cygnets hatch they are immediately taken into the water and their journey towards adulthood begins.
Cygnets stay with their parents until the spring of the following year after hatching. They are forced to leave if they do no do so of their own accord.
They will join a flock where they will stay until they are around 3 years old.
Swans are generally very caring, attentive and protective parents. They will though reject any one of their cygnets if they feel there is something wrong. Swans can detect illness and health problems in their offspring well before any symptoms show.
