>>25310867That's the trouble with stud males. All that testosterone going to their head, along with their territorial instincts. Put two studs in the same paddock, and they will fight for dominance. Hell, put a stud male in with some weathered males, and he will try to mount them. It's not as uncommon as you think.
Plus, that plastic fencing was shit anyway. It was pic related, so all he needed to do was throw his body weight, via his front feet, against enough of the plastic links to break a hole through.
