What breed? Ameraucana mix

[SoCha]

Hi! We have a black ameraucana chicken, but we know that she is mixed with another breed. She lays brown eggs and has a bigger comb than pure ameraucanas should have, would anyone have any idea what she could be mixed with? Thank you!

She isn't an Ameraucana mix or she'd have a pea comb. I'd say she is just a barnyard mix "mix of mixes".

Maybe some australorp in there??
