Light Brahma 14 weeks, hen or late bloomer cockerel

[Lincoln25]

I purchased 2 light brahma chicks from a feed store this spring. At 11 weeks, it was obvious one was a rooster. 3 weeks later the other one is starting to change and now I'm worried if she's a hen or just a late blooming rooster. Can anyone see any male characteristics in these pictures? No crowing, but slightly more vocal lately. Thank you all so much for helping out this newbie!

I started second guessing because her comb has turned more pink and her behavior is more agitated but I think she might be a little spooked by the huge thunderstorms we had. Thank you for calming my nerves!!
