the little ears make me think they are some kind of La Mancha mix.. especially the younger one on the right. the older one doesnt seem to have the right face but definitely the ears.
It's a LaMancha cross. It has LaMancha "elf" ears (that style is not acceptable on bucks for registration, and is what you usually see with a crossbred LaMancha). The face looks Nubian though, LaManchas have a straight or dished face.
looks LaMancha Nubian and the horns look like kikos.. nice looking except for the elf ears.. if it had the "proper" buck gopher ears it would be a very nice buck.
