I am also thinking that it isnt an E.E, as I dont see anything in particular pointing to that. Also SS (if that means Speckled Sussex) I would think that isnt her/his breed because they have white legs/skin/shanks. Can you see ear color? If it is white, you may have a Leghorn. If it is red possibly a Partridge Rock (though Partridge Rocks chicks from the pictures I see don't have that perfect triangle like shape on top of their head), Modern Game, or Welsummer.
