Need help with the breed!

How I can tell several are not pure: I see partial lacing. The ones that are pure are hatchery quality.
How I can tell several are boys: Large and red combs, even for rose combs, its too much to indicate a female. Patchy coloring and early wattle growth are both present.

I would say half/half. I see quite a few girls too.

I defer to you lol. I can't tell how many birds I'm looking at and how many are repeated in the pictures lol.

Ditto on this. In a few weeks, post individual pics of each chick!
