It's still a little too early, but I think they may both be cockerels, based on combs. But definitely post again in a couple of weeks. In the meantime, watch the combs. Growth and redness at this age usually means you have boys.
I disagree that both are for sure cockerels, one on the left likely is but given the right chick looks to potentially be a Leghorn, they can get combs quite early. Personally leaning towards pullet on the right but they are quite young
