He has a sweet face... it will be so fun to earn his trust and train him! Are there books out there on how to work with a wild horse? I would like to read them as well- I bet his senses are heightened compared to a domestic bred horse. Oh, and what is his name?
As this is your first horse and you are going to keep him at home, I just don't think this is a smart choice. Sorry that this is not what you want to hear. But I think a wild mustang is a bad choice for a first home. Do you have the 7' fencing they require?
I think this is a great experience for you. If you run into problems the BLM would have names of people in your area that can help you also. I have adopted 6 horses from the BLM and love every one. Each has their own quirks. Sit in his stall, read to him, talk to him, he will come around. He should be showing a little curiosty about you now. It just takes time. Be patient. And congrats, he is very nice looking. He will grow up to a beautiful boy!
