I have some new information regarding breeding the pullets with the Columbian type colored hackles. I asked about it on an exhibition poultry forum and this was the reply:
"Barring is sex-linked on the Z chromosome: males can have 0,1 or 2 copies; females 0 or 1.
Females with solid hackles simply lack that single barring gene. That part is a pretty easy fix.
What happened was the original cross resulted in males with only 1 copy of barring, and females with 1. When mated together, some of the resulting F2 females could end up with zero copies of barring. This could persist through single-copy males or non-barred females (or even males) on down to what you see today.
If the males you have now have barred hackles, they have at least one copy of barring. I would select for males with the more distinct barring in hopes you are choosing the double-copy ones, and mate them to their non-barred sisters.
You should get at least a portion (half) of the resulting females with barred hackles.
If you get any non-barred offspring from that cross, you know that the parental male was only single copy, and I would probably avoid using him again in the future unless you had other good reason to.
In time with selection for barring and use of test matings like the above, you can reach the point where all males are double copy and the strain breeds true."
This was written by Joe Emenheiser. I don't know him but am assuming he knows what he is talking about. Worth a try, anyway.
