[ChickennDudee]

Okay so when I first bought my Leghorns the man said he didn't know which sex they were so I looked up info online about sexing chicks and found out that I have a hen and a rooster. But one day my neighbor told me that they were both roosters and now that I look at them I'm confused but the one that I think is a girl, her comb is smaller and yellowish than the other one because the other ones Comb is bigger and orangish. They also act like if they were a couple, so I'm not sure what they are please help. Here are they're pictures....I'm going to refer to the one that I think is a rooster as GUY and the one that I think is a hen as GIRL.

GUY

GIRL

How old are they? "Guy" is likely a cockerel and "Girl" is likely a pullet. However, Guy could still be a pullet, as Leghorns develop quickly.
