From this time on, he does not eat, drink, or defecate, and stands only to turn the eggs, which he does about ten times a day.[1] He develops a brood patch, a bare area of wrinkled skin which is in intimate contact with the eggs.[62] Over the course of the eight-week incubation period, he will lose a third of his weight and will survive on stored body fat and on any morning dew that he can reach from the nest. As with many other Australian birds, such as the superb fairywren, infidelity is the norm for emus, despite the initial pair bond: once the male starts brooding, the female usually wanders off, and may mate with other males and lay in multiple nests; thus, as many as half the chicks in a brood may not be fathered by the incubating male, or even by either parent, as emus also exhibit brood parasitism.[63]
