One of my three sheep has got its head stuck out through the stock proof fencing on a number of occasions usually once a week or so. The head and ears are completely out through the fence. Most times i have to cut her out- occasionally my approach gives her enough encouragement to pull out of the fence herself. It is the same animal every time.
I understand that when I got the field fenced off i used a "stock proof" fence and i am now aware that you can get more specifically sheep fencing with smaller apperatures along the bottom of the fence. The openings in the fence are approx 6 inches square.
Is there anything I can do to her to stop this from happening other than replace the whole fence- approx 300metres total?
