Not sure of the breed. I see feathered feet so that narrows it a bit- I would say that they look like roos to me. That much and bright red means just one thing on chicks that size~
OK only saw the first image. In the second one appears to be a single comb the other a rose comb, both look pretty red to me. In the third pic. Not sure, about all but at least one pullet...maybe.
