Okay, today was the first day I've been able to just walk right up to her out in the middle of the pen and pick all 4 feet up without a halter on her head or a fence on the other side of her.
I did find out that I'm really glad she's a (mostly) dark colored horse. She's kind of a filthy pig
I took her out for another little walk and after we got back, I decided to try to brush off some of the ick from her coat. I opened the door to the tack room, tossed the lead over her back, and left her standing in the isle of the barn while I went to get a curry.
I heard a "clop, clop, clop" and turned around to see this...
So, I backed up to the wall to give her some space and she ever so calmly walked in, turned around, and walked out LOL.
So, I followed her out and brushed her down. Then she did it again when I went to go put the brush up. I beat her out that time though.
I messed with Taz just a bit after I turned her back out and, while I was walking back toward the house, I found this and thought it was really cool.
