I made a big breakthrough this morning. I went to check the herd and she didn't try to leave or wander off. I managed to approach her and rub on her neck while she was grazing. I did this for a couple of minutes then went to have a rub on my veteran mare who I have had since I was 11, I then went over to her again and rubbed on her a while longer and then left. I am so pleased I want this to happen consistently before I think about trying to halter her. I was shocked when I saw her too. I knew I couldn't send her back and I feel partly responsible as if I had not sold her in the first place she wouldn't have got to this conition although I couldn't have known this.
