Ostriches are big birds, and they come from desert places. But some farmers in Canada keep some on their farms. They seem to like there, too, though Canada is much colder than the desert places. In China there are very big farms, with 4,000 to 5,000 birds already.
Ostriches produce up to 30 eggs a year for 25 to 30 years. An ostrich is worth $ 10,000 ta present.

鸵鸟是很大的鸟，来自沙漠地带。但是一些加拿大农场主在自己的农场饲养一些鸵鸟。尽管加拿大比沙漠地区冷的多，但是它们看上去喜欢那里。在中国有很大的鸵鸟农场，已经有4000到5000只鸵鸟了。
鸵鸟每年能产蛋30个，持续25年至30年。目前一只鸵鸟价值一万美元。
