The emu, a large flightless bird native to Australia, is notable for its size, speed, and unique breeding behaviors, with males incubating eggs and caring for young. Emus require specific housing and nutritional standards for optimal growth and reproduction, and significant care is needed to manage their health and diseases. The commercial viability of emu farming lies in the marketing of various products like emu oil, skin, and meat, although it requires proper processing and market exploration.
