I would call him a Red Shouldered Silver Duckwing. e+/e+ S/S Ar+/Ar+ ( but with added gene "Hackle Black")
( I used to own one like this only it was a Marans cock)
(All credit for the following info to Van Dort and Hancox "The Genetics of Chicken Colours- The Basics" ,
, Page 208, available from the author at
http://www.chickencolours.com/index.html :
Silver Duckwing with autosomal red coloring the shoulder orange and he hackle and saddle of the
rooster a cream ( selection). Then hens have a more intense red in the breast, otherwise they look
just like a Silver Duckwing hen.
-------------------
Salmon ( as in Faverolle) can look similar but is built on eWh or eb locus instead of e+.
In addition it has the Mahogany gene ( and sometimes also the heterozygous form of the Di [Dilute] gene)
which RSSD does not.

I know what was bugging me. The
Columbian like striping in the hackle of this bird, like in Light Sussex ( my breed). But this bird
does not carry the Columbian gene as in the Salmon colored Dutch bantam, page 208 GOCC-TB, ( (e+/e_ S/S Ar+/Ar+ Mh/Mh Co/Co ). The Co gene would push the black out to the extremities like in a Light Sussex. Instead this bird is a regular RSSD but it has the Hackle Black gene. The Hackle Black gene is what is causing the black striping in the center of the white hackle. Without this gene the Light Sussex would have a plain white hackle.
