Different RIR 10 week old pullet(?)

[Chisrik]

Hi all, I am looking for some help with a RIR chick. I understand it's difficult without pics, but I haven't figured that part out yet.........
So, I have 4 RIR's, right from the time I got them, 1 was a little different. There were sexed, supposedly all girls, and I'm pretty confident it is a female. She has always stood a little taller, been leaner and more streamlined, and slightly darker. Now at 10 weeks, she is about half the width of the other girls, about the same height, but considerably darker. She is a dark reddish/maroon color, with light black tips/lines on her feathers. The others are more plump, and a lighter color with no lining on the feathers. She has no crown to speak of, is not aggressive and has not crowed as of yet.

I'll work on pics, but anyone have any thoughts?
Thanks
RC

well mine are 12 weeks....the roos at that age will have a completely red face, combs and wattles very red and prominant..pullets will have slight redness in their faces and a very small comb and wattle, with some redness, maybe none at all....i wouldn't rely on the coloring of the feathers.. and the roos should be crowing ...mine did..she may just be the dominate pullet.
