A silver duckwing has no brown in between the peppering/stippling, so the second picture is best.

Ok, thanks everyone. The ones with brown feathering were given to me, so I wasn't expecting perfection.
Interestingly enough, you should see the '100%' perfect Sebright rooster he gave me also. It looks just like any other rooster, the tail feathers and all.
I guess I was just his way of culling his flock lol.
On my computer the neck doesn't look silver enough on either picture...to me they both look like cream light browns; the first picture particularly so.
I did have some silver duckwing Welsumers which had mahogany (from breeding with partridge e+ Wellies) This gave a similar look.
