A female mallard duck incubates her eggs. Egg incubation is the process by which an egg, of oviparous (egg-laying) animals, develops an embryo within the egg, after the egg's formation and ovipositional release. Egg incubation is done under favorable environmental conditions, possibly by brooding and hatching the egg.
Egg clutches number 8–13 creamy white to greenish-buff eggs free of speckles. [92] [93] They measure about 58 mm (2.3 in) in length and 32 mm (1.3 in) in width. [93] The eggs are laid on alternate days, and incubation begins when the clutch is almost complete. [93] Incubation takes 27–28 days and fledging takes 50–60 days.
The freckled duck has a standard incubation period of between 26 and 28 days, though some sources have recorded incubation periods of up to 35 days. The female is solely responsible for egg incubation and only leaves the eggs for short periods to feed. The average clutch is seven eggs, but can range between four and 14 eggs. [19]
Average egg size is a breadth of 42.6–44.0 mm (1.68–1.73 in), a length of 58.1–60.6 mm (2.29–2.39 in) and a weight of 61.2–66.6 g (2.16–2.35 oz). [2] The incubation period ranges from 28 to 32 days. The female does all the incubating and is abandoned by the male about 1 to 2 weeks into incubation.
Blue ducks nest between August and October, laying 4–9 creamy white eggs. The female incubates the eggs for 31 to 32 days and chicks can fly when about 70 days old. [16] Nesting and egg incubation of four to seven eggs is undertaken by the female while the male stands guard.
