After googling around yesterday I'm thinking Oogity Boogity is a male. Can anyone help me figure out if I'm on the right track? He's still young. I believe he will be four weeks old this Sunday. I'm trying to figure out of my reasoning is sound, so if you can help me out I'd love you forever. 
He's a barred rock (probable mix), born Jan 21st. And he's massive.
(He's the white speckled one)
I'm thinking he's male due to the large comb size, am I right? He's also much larger than my other two his age (black copper marans and bucket). Lastly his legs are very thick, which I think can indicate a male?
