saipan gamefowl or Satsumadori are a graded malay breed and takes years to develop. If you care to revive the line it would require the original lines and four years of breeding. The issue you will run into as I did was finding a quality hakuro/jap long tail. They have been bred more for plumage...
He just told me there is 1/4 Harold brown in the stag(Madigin over Harold brown, then back to the Madigin cock), but the hen is pure. Is Harold brown a grey line? He told me the Harold Browns shuffle harder but at 1/4 that is his show stock and the pure is brood.
He did say a lot of his birds are white legged but this stag is inbred. The pullet is white legged, but I like dark legged birds. He is molting so when he feathers out I will take pics.
yeah she is with my lemon84, that line started here but did better abroad. My line is from Puerto Rico, bred for speed. The line is dead game and my birds has been pitted in the islands. Problem is they are topically 3-4 to 3-8 and that is too small for the current trend.
If you have the time breed the hens to a good American line cock with a shuffle and if they put out confident stags you will have something special in at least one of the stags. If they are not hatchery birds then they may just be bred too tight and can only produce.
