Is there such a trait? I went to look at a JC registered TB mare yesterday and she had the strangest roaning looking pattern on the inside of her right hind leg.
It was more prominent at the coronet band and then kinda faded out up near the stifle. It definitely doesnt look like scarring of any sort since its not concentrated in one area, its pretty spread out. I guess it could be a birthmark of some sort, but I was thinking about it and I have never seen a TB with roaning.
FYI-she is solid bay with a few white hairs for a star and that's it.
I have one picture, its not a close-up of the roaning, but you can see a TINY bit of what I am talking about. Look at the right hind near the coronet band. In the picture, it looks like shine from the coat, but that's actually white hairs mixed with the bay...
