Hen or Roo?

[Chicken noobie]

We have 4 chicks that are 10 weeks old. Two RIR, an Australorp and Delaware. They should all be hens, but I’m having my doubts about the RIR.

Can you get a better shot of the saddle area?
I'm inclined to say pullet, since if it were a cockerel the face should have reddened up weeks ago and the comb/wattles would be much larger.
However, there appears to be some pointed feathers in this pic and I can't tell if its just the angle on naturally curled feathers, or if they are pointed.
