The picture posted above does indeed look like a Cream Light Brown, but I agree, too young to be evaluated. From whom were the eggs purchased?
Dutch, as with any Single Combed breed, do not do well in sub-zero temperatures, especially if there is dampness and/or draftiness. Large fowl Single Combed breeds may do better than bantams, but any bird with a Single Comb is going to struggle in those sorts of environments.
You may wish to look into birds with pea combs (see the Buckeye thread) as they will be more cold hardy for your location.
