In southwest Oklahoma where I grew up raising ostriches and emu was big business during the 1980's. People from as far away as Japan came there to buy and sell ostrich futures. There was even big auctions for the birds and eggs. And there was also a monthly magazine devoted to the ostrich trade.
A two year old breeding pair would cost around $10 grand.
Ostrich eggs sold for around $800 and baby chicks went for $1,200
I had several friends that raised them to supplement the income of their regular job.
Ostrich meat sold for as much or more than premium cuts of steak at the health food stores. Because the meat was lean and contained no steroids.
