Hi there,
I have 4, month old chickens but am new to raising them so I can't tell the gender, I'm hoping you can help me! (Sorry, there are quite a few photos).
Chicken1

Chicken2

Chicken3

Chicken4

Thanks,
Andrew.

I am no expert by any means, but I'd say number 4 looks like a rooster. Mainly because the wattles and comb look much redder than the others. That's how I knew my rooster was a rooster.

Thanks mrstillery, that would make sense. I always thought it was a roo.
