I have hatched out a few of those barred brown ones from my birds. The father was an over coppered roo that was carrying wheaten. I sent him down the road. The barring does get less as they moult out, but can still be a little obvious on the very heavy ones like the first chick you showed in your post. I sold all mine that look like that. Just tried to get rid of that whole look, including hens that just had golden shafts on dark feathers. Next spring I will find out how that worked out. The one on the bottom has quite a bit of white on the wings, which will probably mostly go away with later moults but likely not all of it when they start out that white. I wouldn't kick her outta the pen though, really NICE coppering on her neck!
