I posted on here when we first got our chickens, worried that one of the Black Aus was a rooster. You all assured me that early tail feathers weren't a sign, in fact quite the opposite. And you were right.
So now I'm worried about the smallest chicken. haha The Buff Orps are only 7.5 weeks, while my other birds are a few weeks older. This chicken is the only one with a comb like this.
He/she is on the right here:
