Rooster or Hen?

[cluck love]

Hello,

We have 4 Rhode Island Red chickens. They are 10 weeks old. When we bought them as 1 day old chicks we specified female.
One chicken is quite a bit larger than the other 3 chickens.
Being pretty new at raising chickens, can you help us identify the larger chicken to determine if it's a rooster?
Thanks!

At 10 weeks, I would expect to see a lot more in the comb/wattles department if it were a rooster.
