I'm not too familiar with Cinnamon queens, but I thought they were a cross between a production red rooster and a silver laced Wyandotte hen. So this one looked like it could be such a cross. But you are right, its body conformation does suggest a cockerel, if not the comb. I'm just confused as to what the bird could be if it is not a Cinnamon queen. TSC should be only selling hatchery birds that are specific breeds or hybrids, as far as I know, but I could well be wrong.
That is the fault of some of the hatcheries, though. They know better but they still sell Easter eggers as Ameraucanas, to the public and to TSC and similar places. But with CQs, TSC should be getting first generation birds. Hatcheries don't sell second generation sex links of any kind, because the birds are only sex linked in first generation crosses.
I did a Google search on cinnamon queens, and most all pictured had more white, but some were darker like that bird. 
Okay, well, in that case, I think this bird, whatever it is, could go either way. I don't see anything definite saying cockerel or pullet yet. If TSC is now selling random mixes as hybrid layers, I don't know what can be done about it, but it's good to be aware of it so we can give better information to people who want to know breed/gender.Not our local TSC.
I was thinking the same thing.
My CQ girls has a rose comb and black feathers.
