Craig et al,
Popularity of varieties can be a tricky situation due to the waxing and waning of breeder interest and goals. For example if one's goal is more toward showing and raise high value birds then it's easiest to start with more popular colors as the pool of quality birds is much higher and it takes less time and effort to produce the desired results. On the other hand, if one's goal is to improve a variety or develop something less popular, more unique and/or something personally important then the quality to start with can be very low. Another issue, I think involves the complexity of genetics in patterned varieties when working with lesser quality or building from scratch. This year, for example, I've gotten nearly all Silver Blues from my Lemon Blue project as my males were silver carriers (now known) rather than gold. Im guessing it will take a few years of test matings to finally be sure of getting a gold carrying blue or splash to become consistent with just the desired color. Fortunately for me, I have the time, patience, and desire to wait it out!
My personal interest is in the genetics. Thus my projects are with laced varieties -currently Lemon Blues and This Fall Brown Red and possibly Birchen. Next Spring I'm hoping to add Silver and Gold Laced. And then as "just for fun" I have Mille Fleur/Calico, Splash & blue (for LB), and Silver Blues (out casts from LB). Someday I may be at the point to have high quality showable birds, but that will be a ways off.
If my goals were to get into showing, in the short term I'd likely go with the more popular solid colors just because of available quality. Starting with the highest quality is more important for some goals rather than to build something starting with lesser if that's what available.
With all of the highly skilled breeders, wouldn't it be great if everyone "adopted" a less popular color to breed and promote to get these colors a jump start to improvement and popularity. Look what Tom Roebuck has done for Lavendar, Danny with his chocolate line, as well as others. All be it a small number, I see more and more newer breeders asking about these "other colors"
