Five Week old chicks, one Delaware is a lot bigger, cockerel?

Edit: Resolved. Last page has rooster pics.

Hello! We got six chicks from Meyer hatchery in late May, and they were supposed to be pullets. They are now just under five weeks of age, and one of them, Kahlua, is quite a bit bigger. This chick also has a larger comb and is starting to get a bit of a voice already. Not to mention the different feather patterning. We didn't expect this, so we haven't kept an eye out for any dominant behavior, and at the moment I honestly can't tell if he/she is displaying any.
We don't intend to cull, but I do already have another rooster and now a total of eleven pullets(2yo roo is the only adult. He is currently with six 2.5mos). We will deal with problems as they come, if they come, and hope for the best.
So, is this big white one a cockerel? Almost certain it is.

Its comb is suspicious, but not enough for 100% certainty. I'd give it another couple of weeks and would watch the comb closely.

I'd say for now just watch it

I agree with the others, just keep a close eye on it and post an update in a couple weeks if you’re still not sure.

Updates. The comb is getting redder, while the others are still pale. Still massive, feathering is getting suspicious, spur buds are just slightly bigger.
NOTE my camera doesn't pick up how red the comb is. It's a bit redder than it appears in the photos. Almost a pale pink lady apple red.

Wow, this is certainly a tough one to guess on. I'm going to lean Pullet by a small %, now if it ends up crowing, I'll change my mind, but for now other than a quick maturing, I don't see the things I would normally be seeing, but others are much more experienced than I so hopefully others can chime in as well.

Size of the bird has never been dispositive for me, but at six weeks that comb is pretty loud.

My vote is cockerel.

I’m going pullet. I see little to no color and as you say it is much bigger I am thinking its a masculine pullet.
