Is this a Roo?

[labelo]

Here is an update at 10 weeks old. No “red” coming in on the wings but is getting some gray. A definite hook to the tail and holds it upright most of the time. Comb is not very red.

I don't see anything that makes me think roo right now. For what it's worth, my parents' EE pullets sometimes have had that hooked upright tail around the same age. I'd say a very pretty pullet!
