It reminds me of an easter egger bantam, but it could be something else. There are many breeds with the chipmunk pattern, easter egger being the most common. You will be able to tell for sure what it is in a couple of weeks.
What a cutie! But I agree with @The Golden Egg5; there are many breeds that have those markings as chicks, so it's hard to say which breed at this point, but I will guess it's some sort of Old English Bantam.
