Birds csn have similar color/pattern, but there are many characteristics that go into breed ID. This bird has a crest and pink legs, an exchequer would have no crest and yellow legs.
Welcome to BYC! The bird shown is definitely not a silver spangled hamburg (though those are lovely birds) -- as suggested above, if you can capture some good, clear photos and post them in the breed/gender forum we can help you get the little one properly identified.
