Beautiful goats, although I don't know anything about the breed standard. Are Bagots kept with their horns on? I always find that goats look so different if they have horns, just carrying themselves quite differently.
I am sure they will become tame, my GG girl that came to me as a kid had been raised on her dam, so was quite flighty. But now, even though she doesn't like to be caught, she can be handled and will always come for a treat.
