The slate-colored legs and what looks like a pea comb (hard to make out) make me think it's an Easter Egger. I have one that looks very much like her that came from Privett. I always though mine sort of looked like a cross b/t an Ameracuana and brown leghorn.
Well, I know the Campine has a standard comb, which is the usual pointed stand up comb you are probably used to seeing. The Hamburg will have a rosecomb with a little unicorn tip on it. Have you found the breeds chicken index? From BYC homepage there is an extensive breeds and sub-breeds index that users have produced with pics and info. Although keep posting here too, cuz I think we all love playing the ID game
