I don't know what it costs to feed them these days (you will need very good fences or they will escape ) , but the ostrich and emu meat sure tastes GOOD . Emu fat has many medicinal and healing uses practiced by Aboriginese in Australia for thousands of years and cosmetic properties too.
NyBoy, did you know that birds native to the United States cannot be used in motion pictures? It is not legal to do so.
To make realistic films, the industry must find a bird fancier who has an aviary with birds which appear similar to the species we are all familiar with.
Some of these are likely to be quite common, like a crow. For cinematic purposes, perhaps a Corvus jamaicensis, for example, could be found rather than a Corvus species from the US.
