I have 5 barred rocks. They are supposed to be hens. They are about 20 weeks old. The coloration on all of them looks the same.Just one of them seems to have grown the comb and wattles faster than the others and so s/he looks different and more mature. Nothing going on with the tail that would suggest rooster.j Do you just grow their comb and wattles at different paces, or could this be a rooster. I can try for a picture tomorrow if it is needed, but perhaps this is obvious to some of you.
