Another musk ox, Thor, is four years old. Knowing he can't win in a fight with the big males, he settles for beating up the chain link fence. Perry Barboza grimaces as he watches the hairy vandal trash the fence. You can almost see the dollar signs flashing before his eyes. And also young bulls have to work out how strong they are and they use the fences to figure out that.
Old bulls do it for advertising.
Everyone beats the fences up. Scientifically, a musk ox in love is a musk ox under a lot of stress. They're working like soldiers on the front line, and they are under continuous stress. We actually do lose bulls at this time of year. We get animals that go down with a variety of strange infections.
