Any idea what her base genes are?

TL;DR
What’s this prairie bluebell eggers base gene/genes?

Here’s a picture of my prairie bluebell egger that died this summer. I was fortunate enough to get some eggs from her and a splash ameraucana rooster before she died and I ended up with two splash roos, two splash and one blue pullet (all are 5-6 months or older).
I’m not super familiar with base color genetics especially when crossed with other genes, so I don’t can’t tell if she’s duckwing based or partridge, or even if she’s both/neither.
I know that pbe’s don’t have color standards and are mostly just leghorns crossed with a blue egger, so she could be just about anything. I did, however, find that she looks pretty similar to blue partridge leghorn pictures I found on the web.
Any ideas? I can post pictures of her offspring of if I need, though only one rooster has leakage from mom seeing as dad’s extended black has dominance over other base genes. Not sure if that would help though.
I’m mostly interested so I can have an idea as to what I might get when crossing her babes to my silver duckwing leghorns. I plan to breed them regardless to have my own strain of blue egger leghorns

She looks either duckwing based or duckwing heterozygous with wheaten. Do you have a picture of her as a chick? Chick down is the best way to determine e base.

I don’t unfortunately. I got her at a couple months old.
Would it be best to wait and see what her grand babies look like? Obvious they will either look E or e+, but like you said, the chick down should help id some other genes too.
Like I said before, I have 5 of her babies, two of which are roosters. I only plan to keep one of them though. I’ll post pictures just for kicks and giggles.

• First two are the same pullet (she’s my fav, I love her splash patterns)
• Next is the rooster with leakage. He might be my keeper; he’s got a better temperament
• Other rooster
• Blue pullet
• I don’t have any pics of the last pullet, as I her splash pattern isn’t as good as the first girl, so I kinda forget about her.
