Bantam Cochin color questions.

[tn_artist]

Hello,
I have five bantam Cochins. The first four seem to be silver laced, but only one has really nice lacing. Question #1: do they usually get better lacing with adult feathering or subsequent molts?
I also have one black Cochin, but her tops of her wings are white. There has never been any other white on her. She hasn't gained any white. Question#2: Do I call her a black Cochin with a color issue, or is there something else going on?
All five came from TSC at the same time. They are 12-14 weeks old.

How old is your Black Cochin? My Black Orpington Bantams get white feathers in their wing tips as well, but they eventually molt out before they’re mature.

They are about 13-14 weeks old. I had never seen a solid colored bird with just a tiny bit of white on the tips of the very longest, two wing feathers before
