Here are the two biggest Mattie babies, the Steel and one of the Chestnuts.
I have had some dark chestnuts, so the depth of color is not the only indication that he's Steel, there's also the solid belly. (Look at those feet!)
Where a Chestnut has a white belly.
And here is the other Chestnut, and the REW.
I can't wait to see how they all grow up. :)
