I was fortunate to find 2 VERY nice male Buff cockerels who do not have an ounce of red in their combs. They are blacker than black. One bird is VERY large to my standards, has a nice round comb with nice crease, just large-and I can tell which is his male offspring by the size of the young. The other male is a nice dark red, but he is very tiny, about the size of a hen in fact and his comb is very oblong and bumpy protrusions all over, also very dark, no red. He produces much smaller males so far. All females hatche dseem to be about the same size, its just the males that carry on the size trait I have noticed. Too soon to tell sex on all, but I have been striving for no red combs and darker buff coloring.
