I knew someone who bred them in the UK along with ostrich , the good news was that he found a steady market for the eggs and meat even just whole egg shells ,the bad news was they they are incredibly stupid they make sheep look like degree students and they only specialty was killing themselves plus they are vicious will peck anything and anyone and have a kick like a mule with out the latters good nature

.
Have you thought about water buffalo ? Smaller leaner than cows the meat has a good market in the east plus they have a reputation of being easy going and gentle .
