Rubbing on Fencing

Have you ever seen a goat running on fencing?? Do you know they are not doing this to scratch?? They are actually looking for a weak spot in the fence to be able to get out of the fence. I caught Carlos doing this the other day. What’s funny about this is Carlos is not in a pen. The fence he was rubbing on, he was on the outside of the fence. Why does he bother? I really cannot answer that. It’s something goats do.
