Blue Australorp and.... ????

[J-Habs]

My chick is about 3 weeks old and i know her father is a Blue Australorp, but I'm not sure who the mom is. Its either a Black Sex Link, Gold Sex Link, or maybe a Speckled Sussex. Another clue is she was hatched from a fairly large egg. I know my BSL lays large eggs, but im not sure the size of the other two breeds. Any clues will be appreciated. Thank you.

She probably has black sex link or gold. But she looks mainly australorp to me.

Ya, the rooster is definitely blue Australorp. I'm just trying to narrow down the 3 possible hens it could be. I have other hens but I know it's not them.
