what breed is my chick?

[murphynhazel12]

so we got the chick in question at tsc from a bin that was labeled "black sex link pullets", but the more she grows the more i think she's not a sex link, lol. she's now almost 2 weeks old, and she's huge, for one, considerably larger than our other two chicks (easter egger and cream legbar) that we got at the same time. and she has a lot of white fluff on her, and her beak and feet are spotty and not completely black. she's also feathering in much slower than our other two, and instead just growing bigger and bigger. I'm wondering if she might be a jersey giant. also i know it's too early but do you think you could guess at the sex? i wonder if she isn't a sex link then she may not even be a she. here are pictures of her and a close up

i tried to get a picture to compare her to the other two in the brooder, it's hard to tell but she's at least a third bigger (she's the one in the middle)

any help identifying her is appreciated, thank you!

Either a black Australorp or a Jersey Giant.
