Emu leather has a distinctive patterned surface, due to a raised area around the feather follicles in the skin; the leather is used in such items as wallets, handbags, shoes and clothes, [86] often in combination with other leathers. The feathers and eggs are used in decorative arts and crafts.
Emu rises. Chasing male emu to mate. June–July High in the sky, approximately horizontal to southern horizon. Male sitting on the nest to incubate eggs (56–59 days).

The eggs measure about 9 by 14 cm (3.5 by 5.5 in) – only ostrich and emu eggs are larger. The male incubates those eggs for 50–52 days, removing or adding litter to regulate the temperature, then protects the chicks, which stay in the nest for about 9 months. He defends them fiercely against all potential predators, including humans.
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.

Eggs of: ostrich, emu, kiwi and chicken. Egg size tends to be proportional to the size of the adult bird, [citation needed] from the half gram egg of the bee hummingbird to the 1.5 kg egg of the ostrich. Kiwis have disproportionately large eggs, up to 20% of the female's body weight. [18]
