I would say he's a gold laced Cochin.
Most of my roosters have crow collars too. Makes for more pleasant neighbors and it doesn't silence the boastfulness of the boys.
Thanks, yours had much better lacing. Is he young and still getting his feathers on our is he growing them in from a moult? Would love to see update pictures when his tail comes in the rest of the way! Going to be a handsome boy!
