Actually, the sale of fertile eggs only amounts to about $40-50 per egg and day old chicks only around $125-150. However, the meat is the big seller. With about forty pounds of trim/ground (@ approx. $10/lb wholesale), thirty pounds of steak cuts (@ approx $14/lb wholesale), and fifteen or so pounds of filet cuts (@ approx. $18-22/lb wholesale). Higher prices are possible with online retail or specialty markets.
The feathers/plumes will bring about $25 per bird total for decent quality feathers. The long bones, tendons, and offal (hearts, gizzards, livers) are sold for pet treats and bring about $25 per bird. Those can be processed and sold online or at specialty markets for considerably more. It's amazing what people will spend on their pets for all-natural organic treats.
Finally, the hides average about 15 square feet and once tanned are sold on a graded system of 1-4, depending on the quality of the hide with scarring and cuts affecting the grade level. Grade 1 tanned hides bring about $30 per square foot. Each drop in grade drops that price about $2-3 per foot.
So, in sum, ostriches can be profitable. They take tremendous work and care in a commercial operation--similar to owning a dairy. The input costs are high to setup and also high to carry over a crop of chicks for a year to the slaughter stage. Thus, most persons interested in farming them will lack sufficient space, time, reasonably cheap feed sources, and the funds to properly execute a true commercial ostrich operation.
