Do you know why Dr. Walker isn't crazy about an association? There are certainly pros and cons, the big con being the fact that then politics and egos can enter the picture. Yeck. But.... especially with Dr. Walker pretty much retired, there needs to be some way to keep the breed going, I guess you could say.
If the goal is to eventually get acceptance in the APA, I believe there has to be a club, with a certain number of committed breeders working something like 5 years to reach that goal. Personally, I'm not a fan of narrowly defined phenotypes, because that can also be the end of some of the productive qualities that poultry "should" have. You see the same thing in any breed of any animal that becomes narrowly defined for the show ring. Maybe that is what he is afraid of.
What Aurora Springs was suggesting, re working within different defined lines with provenance would make sense, at least to me. But still, without an association and people committed to record keeping, it could fall apart down the line, and the breed could disappear again.
