Seeing as you got him from Murray McMurray.....I say Silver Penciled Wyandotte as well. Just hatchery style. There is a good example of what he might look like at http://www.feathersite.com/Poultry/CGP/Wyand/BRKWyand.html. It will be almost to the bottom, row 48 from top or row 16 from bottom of the adult pictures. Labeled: "Another nice pair of Silver Penciled Wyandottes"
