Sorry, I was sleeping & then at work so I'm only replying now.
To all those who wish me good luck, thank you! To those who slam me, each to their own. 
I believe that it is a much happier life to live in a nice grassy field with horses for company & as much food as he wants than to live in the desert with starvation, hunting, thirst & predators to deal with. He would never have a harem out there as the ratio of males to females is too high. I also see no difference to a mustang/brumby being taken out the wild. At least not to the animal (for training purposes, it will be harder with a zebra.)
I was going to just pm Spectrum but I thought it would be nice to see what everyone else had to say & that Spectrum would comment anyway. 
What info & tips can you give me Spectrum? I'm not sure what species he will be but I'm hoping for Burchells as I have more experience with them.
