Brereton (21st Century Poultry Breeding - pp 108-109) writes about the theory of the proposed "Hackle Black" (Hb) gene. I'm still trying to wrap my mind around the entire concept and how it works. But all he mentions is the eb (brown) allele, and the Pattern (Pg) gene. He does not mention the Columbian (Co) gene.
I think we need to start by seeking out the MFC breeders that have closed flocks with no evidence of Hackle Black, and see if it can be pinned down thru process of elimination. But I think we need to start with the allele (e+, eWh or eb), and then move on to the genes.
And has anyone that started with a Hackle Black male been able to breed it out?
All I know is that last year I had 2 different roos - one had red hackles but the chest chevrons had no black. The other had tri-colored chest chevrons, but also had hackle black. No combination of either roo on any of my (well-marked) hens was successful (IMO). So I'm starting over this year - I was able to secure 2 new roos - both with red hackles and tri-colored chest chevrons. If this doesn't work, I'm not sure what direction to take next.
The SOP for Mille Fleur Plumage for both the Hackle and Back in males is "Brilliant Light Orange Vermillion . . . ".
Gail,
I just thought for comparison purposes that I would show you how my project has progressed. I'm sure you know that I have a closed flock. Here are pics of where I started over 3 years ago & where I am today. Obviously I'm not educated on genetics but perhaps this "visual" progression will help others.

This is a pic of Hannah & Emily. They are my first Buff Columbian hens. The two chicks are the result of the cross with my first Roo, Casanova. The dark chick turned out to be Bridget & the lighter chick develped into my "first" Diego.

Casanova-As you can see, terrible type & very dark in his coloring. This is a pic taken when he was only about 10 months old & he does look much better now

Rojo-F4 - notice the black is gone from his hackles, however, the tri color chevrons are beautiful on his breast.
I have just bred Rojo back to the Buff Colombian hens & have 8 new babies. I'm eager to see what the outcome of that cross turns out to be.
Hi Lynne! I was hoping you'd get in on this conversation, as you are one of the few to have a closed flock. I think I've told you before, but it certainly merits mentioning again - I think you hit the jackpot with Rojo! Not only great color, but I think he has some of the best type I've seen in some of your males. I love the nice short (almost invisible) back - the cushion rises right from the base of the hackle. I'm anxious to see what offspring he throws this year!
I can't remember if you went into much detail before about Rojo - is he out of Diego - also with red hackles? Do you remember what color his chick down was? Any chance you have any chick or juvenille pics of him?
