Pure bred breeding pair of yaks

We are offering for sale a breeding pair of royal yaks. The bull carries the golden gene. They were born in July 2013 they both were bottle raised. This picture is just one I snapped this morning while doing barn work so its not the best. I really think these two will through some nice babies. The only reason they are for sale is i have to cut down and our zebras just don't like them to through them out in the pasture. Have any questions let me know.
