That was actually something I was quite concerned with as well. That was a minor considered possibility...that she's not quite roan at all, but instead turning gray. We first thought we had solved the mystery about who her sire was, and narrowed it out to be an appy..... and at that time I thought I could see a blanket forming, and we were curious if she'd turn gray..but then we realized her father couldn't be the appy we thought it was based on the colors she's turning out to be. If her father was the appaloosa we thought, she'd have to be sorrel, or bay. Period. And this past summer, she definitely started lightening up...do you have any more pictures of your little guy that turned grey?
