Leghorn and Auracana, where?

[Feather queen]

I am currently working on separating my mixed flock into there breeds, but I have a few who I don't know were to put them.

Free rangers flock:
Australorp x silkie - rooster
Isa browns
Cross-breeds

Silkie flock
SDL AND GL Barnevelder flock
Silver Spangled Hamburg flock and Bantam flock??? (Possible, lost roo)

Other hens:
2x exchequer leghorn hen
3x lavender auracana (im thinking barnevelder flock? For olive eggers?)

Which flock would I get the most unique or pretty colours in and what would there offspring look like?

Kind regards,
Feather Queen
