Gordon & Bessie attack the Fence!

I have finally found the culprits! We have had to replace the plastic electric fencing posts with wooden posts, because we keep finding them strewn around the field with the electric tape flapping about all over the place.

We now know that Gordon likes to head butt the posts! Hopefully the wooden posts will stop him destroying all the fencing. However at the same time Bessie has been helpfully winding the fencing tape around her horns and then either breaking it or dragging it around the field. Not too sure how we are going to stop her doing this.
