I can't tell the color of the legs or if the chick has "muffs" on it'sface by the picture. It looks a lot like my golden campines in color if it has slate blue legs and no muff. If it has muffs and green legs it is an easter egger I would guess. I have 3 that look like that and we are constantly mistaking them for our 2 campines.
Here is a pic of one of my BSL pullets...yours is close, but not quite the same:
yours has different colored legs too, but then here is a shot of my other one, she has dark legs like yours....
