Anyone interested in helping me identify a chicken?

Hello!
My wife and I adopted chickens from a coworker who was moving a few months back, and when we did so we took his word for it that they were the breeds he said they were. I can pretty well confirm that we have a Rhode Island Red and a Barred Plymouth Rock, but our third hen has become somewhat of a mystery.
We were told that she was a white leghorn, which I didn’t question until she went SUPER broody, at which point, having heard that leghorns almost never brood, I looked up traits of the breed and found that the bloodiness isn’t the only mismatch.
So, confused, I turn to you!
She’s a white chicken with some grey and black patches here and there (more of a dirty white than any sort of noticeable pattern), has slate legs, a single comb, and is the smallest and most skittish of our hens. My understanding is that leghorns tend not to brood and almost always have yellow legs and a pea comb. Included is a picture of her with her chicks (not biological offspring, we gave her fertilized eggs from a flock our neighbor keeps of Easter Eggers and Trye Blue Whitings).
Any help would be greatly appreciated, as I am very curious
Thanks!

She is an Austra White. The result of crossing a Black Australorp cock with a White Leghorn hen.

I agree with @Brahma Chicken5000

Leghorns have straight combs. Usually large ones.

I too have a yardfull like these that I purchase specifically from a Texas Hatchery. Ideal Hatcheries. The bird you have I believe is what they created as a great laying hen <300+ eggs a year and a great meat bird if fed correctly. They crossed a white leghorn with a Cornish I think. They call it an " Ideal 236"

I have since crossed an Ideal 236 with a very white fluffy cheeked Americauna. I got a white rooster with light brown saddles and a perfectly straight red comb.

I’m not really sure what it is, but it looks very similar to my light blue Andalusian!

Beautiful bird.

Thanks everyone! I had seen a few pictures of Austra Whites that I thought looked like her, but had just thought maybe she was a leghorn with some dark patches. the excellent mothering and the slate legs threw me when I started investigating. Here are a couple more reference pics from a few weeks ago when the chicks first hatched (they grow so fast!)
