I have one tiny girl too, she always was. One of the more feisty of the bunch too! Look at the combs head on. I find here at an early age, the boys' combs are wider. Put all the hints together and you may have a better guess. Truthfully, I really love my boys the best! Can you not have roos there?
X2!! I love my boys the most too!! They are all so sweet and more friendly than my girls.
