All jokes aside, I get the same thing from some bucks. I think they are pretty good at figuring out males from females. It's a dominance thing. They don't bother girls because they already assume that they are dominant over them. In their minds there is one thing they can do to another male that is the ultimate display of dominance. (Goats are so nasty.) If you watch two bucks, they will walk up and blub at each other and try to mount. If equally matched there is usually a fight at this point. If one feels outclassed from the start, things might not go well for him. Just your basic goat psychology. Just don't drop anything and you will be fine.
