@ mz_angie1987,
At least it means that goats are extremely peaceful animals. They do not even get angry after you knocked them down multiple times. The brown one was just being playful and attention seeking. I am sure he meant no real harm when he knocked down the black goat. The black goat was also not hurt at all, and I respect his peaceful attitude of not getting pissed off at all after the repeatedly "abuse".
From the video you can clearly see different goats have different personality as well. I am sure not all goats are attention whores and crazy jumpers like the brown one in the video.
