My opinion as best I can see from this picture; This is juvenile feathering which will still change quite a bit but it does give you a good indication of color placement. The cream/salmon color is in the right place, and this might darken some as the bird matures. (ABA silver standard: light salmon) Seems unusual there is white bib on the top front of the neck, unless this is camera glare? Does the cream color continue to the muffs? It does seem odd that the bird has a few dark feathers on top of the head and solid white on the neck. Again this might change over time IMO. (ABA standard calls for Head, Male: silvery white, Female: silvery grey)
Yes, the shafting is visible as the white shaft in the dark feathers. This will likely remain as the bird grows out. But it is evident in almost all bantams that I have seen. It will be a slow process to reduce this flaw, gradually over time. I get the impression that the Silver LF have made more progress in this regard. Maybe some of those breeders can add their experience with this issue?
