Yes the darker BLRW (well thats what the eggs they hatched from said anyways ) has a single comb. The rest have pea. The really dark BLRW in the third photo is the one I was really thinking roo (and the Frizzle). Thanks ya'll!
Here is a group shot of most of my birds. They are nine weeks old. Will update with individuals if need be Just looking for gender. I know they're BLRW, SLW, Frizzle EEs and Ameraucanas. Thanks!
