Duck Breed?!

[xKaitlin]

Back in March I got day old ducks and ended up with 2 drakes and 2 ducks, once they were 4 months I got 3 more girls 7-12 weeks old that were mixed but I still can’t tell the breeds as I am new to this.
I was told I was given a Welsh harlequin (biggest), buff Orpington (smallest) and a Swedish Blue.
The two brown ones I am unsure what they are mixed with so I’d appreciate any help!

Here is an uptodate one showing their wing bar

For anyone interested here are my original purebred 4
2 girls (Aylesbury and Cayuga)
2 drakes (Khaki Campbell and Welsh Harlequin)

The bigger one looks to be Welsh Harlequin but the other looks like a Khaki Campbell to me.

Aw was really hoping for a buff Orpington,
Does the welshie grow whiter over time or is she a gold variety ?
(I’m new to duck genetics so idk much about silver or gold welsh harlequins)
