He is attractive but has way too much white. From the draft SOP:
Tail: Main Tail—gray, evenly barred.
Sickle and Coverts—light gray, barred, some white feathers permissible.
Likewise on the hackles and saddle feathers:
Neck: Hackle—cream, sparsely barred with gray.
Shoulder—cream, barred with dark gray, some chestnut permissible.
Front of neck—same as breast.
Wings: Fronts and Bows—dark gray, faintly barred, some chestnut permissible.
Coverts—gray, barred, tipped in cream.
Primaries—dark gray, faintly barred, some white permissible.
Secondaries—dark gray, more clearly barred.
Back: Cream, barred with dark gray, some chestnut permissible.
Saddle—cream, barred with dark gray, edged in cream.
Where i would expect to see cream, I see white. While he looks like a nice young rooster, I would not use him for breeding. That said, if your female looks very good or is darker than she should be then it would be worthwhile to experiment to see what they produce.
Post a picture of your female.
