What breed chickens are these???

[CK Chickadilly]

They are brother & sister, approx. 3 - 4 months old. They were given to me & the gal thought they were Banties. They are bigger than my Banties now. They are full size I guess.

She has a tuft of feathers on top of her head. His neck has changed to the golden color & hers is starting to change but not as dark as his golden color. They both have the dark gray to black legs.

I am just curious if anyone can identify what breed they are.
Thanks!!

I'm no expert but they look like a cross to me

The second one looks almost like a Polish cross to me, but I'm not that good at IDing yet....

They look like Heinz 57 X OEG..

But they are still pretty.
