Guess the sex.. Sorry in advance

[mcguffinvalley]

I hate these kind of posts, so I'm sorry for this. I'm worried I have a roo. Can you confirm? These are all 11 weeks old with the same hatch date. My light Brahmas are getting red, but not near as red as the one in the first pic. My buff brahmas aren't even pink yet. I'm new at this and read about the comb being different, but they all look the same to me, other than either grown out or not. Tails all look the same.
Thanks for your input

somebody that raises those could probably spot it instantly, but as a general observation id say yeah, that one is looking mighty red lol .. the pidgeon toe stance i loosely associate with manliness also ..
