Ok, so I told Joe I would re-post this formula. And in reading it again, I realize I screwed up in my recollection of it
Resolutions formula is a little more complex than what I remembered.
Here is his post on backcrossing:
Per Resolution, link:
https://www.backyardchickens.com/forum/viewtopic.php?id=278349&p=6
Start with a female line that you know absolutely are full sisters. Save one or two of their full brothers.
Locate an unrelated rooster that you have personally hatched from a dark egg.
Pair this rooster with the first female from your well represented female line.
Select out the darkest eggs from her first clutch.
Hatch them. Select the rooster from this clutch that has hatched from the darkest egg.
Breed him back to his mother.
Repeat the process again and again for 8 consecutive generations.
If for some reason the original matriarch dies, replace her with her closest relative.
Her full sister is the best candidate but remember- you are taking two to three steps back everytime you outcross to even a related female.
Once you have arrived at the eighth generation, you can now breed the progeny interse, that is brother to sister.
Or, better yet, breed them to the close relatives of the mother. You can keep any of the birds not used for breeding but I would send them off to save room and prevent confusion.
You really want to just be as conservative as you can be. This means you set up separate enclosures. Your breeders don't get to run loose. You have to feed them like wild junglefowl and care for them as if they are delicate hot house flowers. This means no crumbles, no mashes no pellets- just whole grains and an animal protein infused pellet.
Mazuri makes an exotic pheasant extruded kibble and of course my company makes an extruded zoo pellet that's 70% more nutritious.
The French feed cockles as their mystery ingredient and lots of crustacean meal- pieces of shrimps and such left over from cooking -so close to the sea.
But for you - inland its too risky to put out material that may become a disease vector. Great genetics help. You can nevertheless, select breed towards that point using blegh stock.
We've experimented with different breeds and it is almost always the same result. We end up with better egg shell colour when we backcross- provided that is what our founders -that's the trait we are isolating and encouraging through selective breeding.

Yes- each generation of roosters is another generation bred back to the original matriarch. By the 8th generation his mother will also be his great great great idk how many grandmother.
drom~ Thank you for posting this.....this is what I was referring to when I responded to flgardens inquiry, I just didn't have enough time to type it all out when I was posting.
I started out with 2 Davis roosters and no hens......later after the boys were 1 yr old I finally got 4 Davis pullets, I bred these birds together kept the female offspring that I wanted, I did not care for any of the male offspring produced from these birds and eventually got rid of the 2 original roos. While in the process of growing the offspring out I located some one here (in the same state) that had a closed flock of Davis birds (referred to her by Bev, unfortunately I understand she is no longer breeding........huge bummer on my part.....I so wanted more eggs from her) hatched out those eggs and kept the offspring that I wanted, 2 roos and 5 girls. At this point I now had 2 pens of Davis birds, not that closely related, but still of the same lineage. I bred the 2 roos from the second batch of eggs to my 4 original pullets and kept the good female offspring from those crosses and a few males to grow out, I did not like any of these males either. So I keep one of the original hens in this pen and her daughters and they are still being crossed to one of the second batch roos, essentially speaking most of the females produced from this cross are being bred back to their father and grandfather. Still in search of a nice male to be thrown out of this pen so that I can grow out and breed a new grandson back to his mothers/grandmothers each year.
On the flip side...........I have a completely unrelated rooster that I crossed to my original 4 Davis pullets to introduce new blood and other nice qualities that he lends including his egg color. I have grown out some very nice bodied and dark laying females from this cross and have now introduced these females to my pure Davis pen and have first generation from this cross growing out now with the prospect of 2 nice males. I am hoping to produce a nice male from the 1/2 Davis and 1/2 unrelated roo females by breeding them back to my Davis roo. I also still continue to breed the completely unrelated rooster to Davis hens and a couple of his daughters from the first Davis/unrelated crosses for hopes of a nice male someday and I have increased the diversity of my gene pool at the same time.
Now to add to that.......I have again added another batch of Davis birds to the equation, that I had shipped in this summer, new blood so to speak, but still of the same lineage. None of the roosters are worthy of keeping, the females are great and I feel that by crossing them back to my Davis roo that I may have a chance at a nice roo while maintaining egg color genes from the same lineage. I also added a couple of females from this last batch of birds to my completely unrelated roo's pen.
My goal is to create my own line and eventually breed in more of the unrelated roo's blood, borrowing a few well established qualities from the Davis birds, I have found combining them with the qualities of the unrelated bird creates some very nice birds that are more of what I would like to see in my flocks.
