"Ostriches usually weigh from 93 to 130 kg (200 to 285 lb) per Gilman, D. C.; Peck, H. T. & Colby, F. M. (1903). The New International Encyclopædia. Dodd, Mead and Company, 497."
The above answer is not quite right. I suspect they are talking about wild ostriches but even so the answer is a little off. There are different lines of ostriches and they vary in size. The African Black birds are close to the size quoted but with good husbandry there are three main types of ostriches. The smallest is the African Black, then next in size is the Blue and the largest is the large Red Neck which can top out at over 10 feet tall and 500 lbs. When farming ostriches they reach a minimal weight of 220 lbs at 8 to 12 months old.
