Is this a hen or a roo?

We just started our first flock of chickens, now about 9 weeks old. We have two ameracaunas and a barred rock. They were supposedly all girls but I'm started to wonder about one of the ameracaunas. Take a look and let me know what you think.

That's a pretty Easter Egger pullet you have there.

Definitely a pretty pullet.

Thanks all. I was getting nervous because her comb is a bit bigger than the other and her tail a bit longer but I know there's some natural variation. Appreciate the reassurance!
