I think (as much as I hate to admit it) it is a 'he', esp. since he/she is feathering in much slower then the others (which I was told is another sign of a male). I guess we will see. My problem is I really wasn't going to have any roos (for noise), but goodness, I love Emmy so much (so still praying SHE just has a bigger comb for being a girl! lol) Thanks guys.
I've had Cochin hens with bigger combs as chicks. That being said, at 4.5 weeks old and that much comb I'd say that is a little rooster you've got there. My Cochin roosters were super sweet and relatively quiet (even though there were 2 of them). Good luck.
