Not necessarily, with 5 toes and feathered feet, he is at least part silkie, sultan or faverolle. If silkie comb could have come from that parent. Not to say that the barring couldn't have come from dominique, just don't base it upon the comb.
Barring could be from rock or dominique or marans or ... I agree w/ Speckled Hen that it probably has some silkie in it's background, but I bet it is more than one generation back.
