What are these two bantams?

[blackout1983]

I bought D' Uccle (what I was told) about 3-4 months ago, the breeder said they are porcelain and mill flue but I've had bearded boosted roo in the past and have a sweet caramel girl who's about 2-3 months old and these two are no where even close. I can pin them to one breed so I'm thinking maybe a crossbreed but I need help to figure out what breeds if cross or what breed (none mixed)

Mixed breed for sure and no feather leg in ancestry, their legs are too clean. They were either crossed or mixed with something crested.

That's what I was thinking but everytime I thought I had found a breed something would be off. Wish I could figure out what the mix was
