Actually David Rogers birds kick Cy's rear. His are actually bred from a pure onagadori hen to create his line. Cy, while he has great birds and are of onagadori decent, they are like 80 years old from the original crossings. Most all onagadori traits have been lost in the various out crossing since then. You can still get a few non molters out of his line, but most molt annually to every two years just like a normal phoenix any more. I have several birds from Cy here, and they are very nice phoenix, but that's all you can honestly call them any more, phoenix.
David on the other hand knows anything and every thing about the breed and has dedicated his efforts to solely selecting and breeding exclusively for onagadori traits. The results show. While he still wont call them onagadori, they are pretty much as close as you can get
His primary male is between 8-10 feet already and still going strong. Cy's birds just can no longer compare to what David has going.
It's not just feather length, leg color, feather type, multiple feathering, etc all are what make onadadori different from phoenix.
I believe it's like 11 genes in the tail alone they have to carry to be a true bird, each grouping of feathers has to have rapid growth, non molting, and multiple feathering, the type has to be very fine, thin and soft as well.... Bunch to it other than just a long tail.
For any interested, Davids birds can be seen on Onagadori.net
And yes, in the Sticky section of this forum, there is a 100+ page thread for phoenix, lots of nice pics and info on them, feel free to check it out, and keep this one going as well
