Bless em, your grey's look like they have been enjoying themselves in the mud, they look like my two wooly and muddy at least mine are already brown though, I think they look so cute with wooly coats don't you just love winter.
Ahhh bless them wish my fields were as dry as yours after all the rain up here its hard finding dry land, and its snowing on and off ( too wet to lie at min)and is that sunshine you have, lovely horses you have.
