Is this a rooster?

Just concerned cause it’s made changes in the past week in it’s comb and size than the rest

chick sounds gender conflicted - maybe a couple more weeks will tell, if you post new photos then.

I wonder if this isn't a black sex link cockerel that got mixed in with the barred rocks. I agree, otherwise, that the color says BR Pullet, the comb says cockerel. If its a black sex link, then its a cockerel, just because its barred.

@Frazzemrat1 might well be a back sex link that make more sense
