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.

The common cuckoo is an obligate brood parasite; it lays its eggs in the nests of other birds. Hatched cuckoo chicks may push host eggs out of the nest or be raised alongside the host's chicks. [17] A female may visit up to 50 nests during a breeding season. Common cuckoos first breed at the age of two years. [2]
Each female lays three to seven light-blue or, rarely, white eggs. The female incubates the eggs, which hatch after 13 to 16 days. The young cannot care for themselves upon hatching. The female broods the chicks for up to seven days after hatching. Fledglings then leave the nest 15 to 20 days after hatching. [11]

Generally, the nests are sheltered by ferns and small bushes, or placed in a dip or rocky hillside under an overhanging rock. About 7 to 14 eggs are laid. [8] [24] [32] The eggs hatch in about 23–25 days. In captivity they can lay an egg each day during the breeding season if eggs are collected daily. [33]
Early season nests see an average of 9.0 eggs per clutch while late clutches see an average of 6.4 eggs per clutch. There is an inverse relationship between egg weights and laying sequence, [ 29 ] wherein earlier eggs are larger than eggs laid later in the sequence.
