I disagree, they look partidge (for hatchery birds) before the spots come in.Maybe... I asked this same question about my SS genders here a while back. The combs on SS seem to get big early, but both of mine turned out to be girls. I'm not good at the gender guessing on some breeds though.
I have to agree that they look like a really cool SS mix with something else... partridge maybe? I have only seen SS that have whole bodies that look like your babies' neck speckles. They're really pretty though.
Here are mine that hatched on 3/4.
