I am having a difficult time telling if my 3 barred rocks are cockerel or pullets. Can anyone tell me what I have? I think the two to the left are cockerels and the one on the right is a pullet. I have tried and tried to read on how to tell the difference. I get to a point where I think I can figure it out, then I go outside and look and still shake my head. I give up. They are about 12 weeks old. Any help would be greatly appreciated.
