Mixed flock of hopefully pullets

[Gallinarium]

I got a bunch of different breeds from Murray McMurray hatchery, sexed run females. I think I know what breed each chick is. I'd like a confirmation on the breeds and gender. I used a question mark where I'm not certain of the breed. The rest are just cute pictures. They are all six weeks and one day old. Note: sorry for the blurriness and double heads. Chickens will just not hold still.
The breeds and varieties I have are:
A white Leghorn
A red Leghorn
A silver Leghorn
A single-comb brown Leghorn
A rose-comb brown Leghorn
A black Minorca
A buff Minorca
A Red Star
A Whiting True Green
Three Whiting True Blues

Cute bird pics ahead!

Alice Von Fluffypants, Whiting True Blue?

Amaranth, Amara for short, red leghorn.

Argenti, adorable little runt, silver Leghorn.

Blondie, very snooty, white Leghorn.

Buffy The Chicken, buff Minorca.

Jasmine, very pretty, Whiting True Green?

Rachel, single-comb brown Leghorn?

Rosalie, surprisingly friendly, rose-comb brown Leghorn?

Sally, flies up on my head when I open the coop door, Red Star.

Sapphire. She is definitely a Whiting True Blue, but she's the only one whose gender I'm worried about.

Spade, also known as Spectacle Spadey, Black Minorca.

Valentina, Val for short, Whiting True Blue?

Note that most of the ones with combs other than single are Whiting True Blues, but one of them is a rose-comb brown Leghorn. I don't know how to tell the difference between rose combs and pea combs at that age.
If you want to see them younger, because, you know, cute chickie pictures, here's a link to my earlier thread: https://www.backyardchickens.com/th...tures-unless-you-need-another-reason.1370395/
I would appreciate observations, and I hope you think they're gorgeous like I do. Thanks for reading!

Valentina is the RC brown Leghorn.

Is your silver Leghorn tiny? We got one last year and she's small compared to the other Leghorns.

Oops, and I named Rosalie for her comb... Now what?
Yes, the silver Leghorn is tiny compared to the other chicks. I assumed she was a runt. So it's genetic, then?

Ours is smaller than the other variety Leghorns, with a stockier build and a much smaller comb. For a while we wondered if she were a Phoenix or some other breed by mistake. She's perfectly healthy though and more friendly than one would expect. We can pick her up easily. She does have a rather pointy set of spurs too.

I don't suppose you have any pictures?

Any ideas on Sapphire's gender? (The blue one.)
