Last chicks gender?

[sekeyslaks]

I’ve already identified this 9 week old chicks six siblings but I have yet to pin down whether this chick is a hen or roo? It is the same size as my boys basically twice the size of my other 2 girls.but it’s coloring and personality and comb makes me think it’s a secret female.Especially since I am already suspicious that this chick came from my abnormally large RIR/mix hens.(I will share pic of them if requested) So boy,girl,or undecided?
