The swan's nest is on the ground near water and about a metre across. Unlike many other ducks and geese the male helps with the nest construction. Average egg size (for the mute swan) is 113Ã74 mm, weighing 340 g, in a clutch size of 4 to 7. The incubation period is around 34â45 days for swan.he females will lay their fertilized eggs in a single communal nest, a simple pit, 30 to 60 centimetres (12â24 in) deep and 3 metres (9.8 ft) wide, scraped in the ground by the male. The eggs are incubated by the females by day and by the males by night.
