butting behavior

We have a pair of 3-year old female goats (cross between Nigerian Dwarf and Pygmies), bought as pets for my older daughter. The lead goat, Gaby, has increasingly problematic behavior--butting me and my daughters (ages 7 and 13), constantly rearing up in challenge at us, etc. We have covered her...

Hey, Just wondering if anyone has advice on how to keep billies from becoming aggressive and wanting to butt? I have a small Myotonic herd. 1 billy, 3 nannies and 1 weather. The billy has and still is friendly but sometimes he will put his head on me and push. What is the best way to get him...
