Ameraucana Cockerel or Pullet? (3 months old.)

[Not-so Slick Chicken]

Apologies about the poor quality picture.
Also, hoping I put this in the correct section!

I ordered from a hatchery at an odd time (winter) and the chicks are now 3 months old.
I believe one of the sexed pullets will turn out to be a rooster.

I can have roosters, so this isn't a problem. I also can get reimbursed by the particular hatchery I ordered from for the unintentional rooster, and have over a month left to confirm and inform them.
This post is mostly just me hoping to get some opinions and explanations about what to look for. I've been around chickens my whole life, but these are -my- first chickens and this is the first time I've really spent time with any.
I've tried looking online, as well as on here, and haven't quite found what I'm looking for. But I'm just not that familiar with the appearance of this breed.

The question is about the "Black Ameraucana".
I also have a Splash Ameraucana of the same age who certainly appears to be a pullet.

My reason for thinking cockerel is mostly the comparison of the two Ameraucana. The Splash has a much smaller comb. And that's kind of all I have at this point. I'm having difficulty spotting if any hackle feathers are much different from any of the other pullets.
These are the only 2 Ameraucana here.
The pictures are recent. The chicks were 13-turning-14 weeks.

Also, at 14 weeks, should the white on the muff and beard have disappeared? I'm not looking for show quality. Just curious as I couldn't find info about when all the white feathers leave the black ameraucana.

Hope this wasn't too scattered! Thanks all for your time and looking.

The black one is absolutely a cockerel. Crossed with the splash pullets, they would make 100% blue chicks. So that could be a silver lining.

Thank you. If I may ask, is it the comb that's the confirmation? I'm not sure if Ameraucana hens have pea combs that size or what.

*edit. I mean, are there other features besides the comb that are visible at this age?

I had nearly purchased a Black Ameraucana cockerel, but ended up not doing so.

I've wanted to experiment with egg colors (we've always had mixed flocks, and ended up with many variations in egg colors)

I also have splash, lavender, and austra white pullets. All which will pair best with a black rooster.
(The newly hatched Lavender and Splash looked... identical...)

It's quite convenient, for me, to have this particular pullet not be a pullet.

The only real bummer is it'll mean one less hen laying a blue egg this year. *shrug* But, at least I don't have to find a new rooster. (*original cockerel chick didn't make it)

The last picture shows male specific feathering, especially in the tail with all of those green sickle feathers. He also has the shiny, pointed feathers coming in on the saddle and the shoulders.

The comb is always a good indicator, too, both redness and size. His comb actually isn't too large, but the other factors were clear.

He looks good and healthy, and will make a good parent if you choose to raise chicks from him. Since he is Ameraucana and not an Easter egger, he should pass on a blue egg gene to all of his offspring.

Crossed with the splash Ameraucana hens, you'll get blue Ameraucanas who will lay blue eggs. Crossed with the Anconas, the eggs will also be blue, maybe lighter in shade. Crossed with a brown egg layer, the female offspring should lay green eggs.

The black one is definitely a cockerel, the other one is probably a pullet.
