Any bird would look better than those birds.
The birds in those photos are yellowed from sun or even genetics, have poor body conformation, poor color...there's a whole plethora of issues. But, the birds are supposed to be compared to the STANDARD. Not against each other. When that happens, it is because two birds are so close to the standard that you are selecting which bird is closer to the standard. If no bird in the category looks anywhere close to it's "assumed" breed, it simply should not be placed.
I'm not knocking your Delawares, but they are pet-quality and should be sold as such or eaten. Sorry if that offends you or your breeding decisions, but it's how I feel on this subject.
OP, the false barring or smuttiness may go away as the birds age, or they may not. All I know is that if I were breeding Delawares and my cockerels showed the patterns in their saddle feathers, I would not use them for breeding, even if the molt removed it from sight.
