Greetings! Is this mare at your farm? Do you see her everyday? If so, i can offer ideas for getting her mind on you. I am a pro trimmer, but others can help with the hoof issues. First treat fro serious butt crack infection.
The first thing you and anyone who wishes to help, need to do is get her confidant about humans. Are you familiar with The water hole rituals? She needs to Choose to be with you! This will take a LOT of time! Build trust. Find her itchy spot. If you want more info, i will love to explain more details.
