I have noticed that most of the birds on the west coast are of the tall upright strain and most of the the birds I have seen on the east coast are the shorter thicker body strain Ko Shamo. I have acquired one of the upright strain cockerels and two of the shorter strain cockerels and a shorter strain pullet. I had the upright cockerel in with the shorter strain pullet and that was the pair I was having problems breeding from. I now have the pullet in with one of the shorter male cockerels that is real small like a Chibi type. I am going to try and breed for that type from them. Skitter those are some nice blue Ko Shamo.
