Oh boy, oh boy, oh boy! (Hope not!!!) I can see why you're concerned. I have a hatchery SLW that had a red comb and wattle area at 5 weeks also, but her comb was smaller than those in your top two pics. She was also quite leggy and had me worried. Now at 14 weeks she is definitely a pullet, although I think she is more silver SPLOTCHED than laced.
My point is I think the SLW hatchery birds have a lot of variation, and you should wait a few more weeks to be sure. Look for development of a lot of white on the wings, which will show a male. It would be unlikely for you to have gotten 2+ roos in such a small group, unless someone confused straight run with sexed pullets (or was sexing with a serious hangover
).
I think you still have a chance for pullets. Hope for the best, but prepare for the worst!
Best wishes!
