What breeds do y'all think my tractor supply mixed bantams might be?

The first three are Cochins-mottled, black and possibly gold laced. I have a ton of black, smooth and frizzled and one coming in gold laced that likes like the third one with that but if brown on its face. I never end up finding mottled until a few weeks ago. There was only one. Here's a cockrel.
The rest are all silkies.
