Well, several breeds have 5 toes. Dorkings are smooth shanked and come in a spangled color I think. Faverolles and Sultans have feathered feet and Houdans have a top hat. Silkies also have 5 toes and have black skin and characteristic feathers. There may be other breeds I can't think of off hand.
From the picture I am going to guess a Dorking or Dorking cross, but if there are feathers on the feet or a top hat I would switch my vote. The feet are not black so I doubt Silkie influence.
Yes, pictures of the head including comb and full side body shot would be most helpful.
