Differences I go by in addition to comb are the bars on feathers and appearance of legs. Note overall the cockerel appears lighter which is the result of the dark bands being narrower than light bands on each feather. Legs of cockerels are larger early on, but pullets in strains I have tend to retain the gray look to scales. Latter difference goes away since pullets and hens eventually get the yellowish legs until they get into serious laying.this picture of my 5 Dominiques and 1 BA was taken last year when they were just about 4 months old-they were all hatched on the same day-I did have one rooster out of the six-you see how much larger his comb and wattles are than the girls.
