Okay, she is just the sweetest thing! I went out this afternoon and started messing with her. Within about an hour I had a halter on her and she was tentatively leading all over the round pen. She'd still have those "ZOMG, what is this thing on my face" moments, but they were few and far between. The thing that took the longest was just getting a hand on her that first time. After I finally touched her, it was less than 5 minutes and I had the halter on and I was scratching her all over her head, neck, and even a bit onto her back and belly (I didn't want to push it too far and cause a freak out).
So, I've got some new pictures of her "gentling" LOL.
Here, I had just got the rope on her and she was having her !OMG! Moments
Here, she was finally starting to face up when I would put pressure on the rope
Then, I just put her up in the small pen and took my time working closer to her
She's thinking about smelling my hand
Her very first human touch
She was really enjoying me scratching under her jaw
Then, I was able to slip the halter on (I know it's too big, but it's all I had)
