This method is called the \"7 Diamond Pyramid\".  It is used to recreate a genetically superior bird.  Here is an article about it;


Line Breeding method



With breeding birds I have never followed a great system. I tended to breed best to best with occasional line breeding.
Jim told me of the\' 7diamondpyramid\' which, if followed closely will always breed birds true to the original parent birds.
This is particularly important if we start with  good birds.
However I (and how many of you) have had good birds to breed from and within a couple of seasons was breeding birds inferior to the original couple only because I did not use a scientific method.
Jims Method is as follows.

the\' 7diamondpyramid\'
1st generation Parent Cock (C1) X Parent Hen(H1)
2nd Gen Best Hens to C1 Best Cock to H1
3rd Gen Best hens to C1 Best cock to H1
4th Gen Best Hen to C1 Best Cock to H1
5th Gen Best Hen to C1 Best Cock to H1
6th Gen Best Hen to C1 Best Cock to H1
7th Gen Best Hen to C1 Best Cock to H1
He says that if this system is used then the end result at the 7 th gen. is a bird identical genetically to the parent bird and one which will breed true to type as the parent bird was.  

Obviously other lines can be started
I would appreciate any comments on this. I am onto my third generation with some of my birds and have been very pleased with the results so far.Appreciate any feedback.  BTW his Muscovy ducks, which he sells to restaurants , are enormous and the diet he feeds his birds on is quite amazing. More on this later.Lindon

Here is another method from an article by Dr Everrett of the SPPA.


The first system I would introduce was utilized by William Morgan, of Morgan Whitehackle fame, and some of the English cockers.
It is a form of breeding known as “3 times in and once out.” This system was used to produce, in cockers’ terms, a “pure strain.” The following chart will explain how the system works. First Generation Hen Cock ½ hen ½ cock
Second Generation Hen to son Cock to daughter ¾ hen ¾ cock
Third Generation Hen to grandson Cock to granddaughter 7/8 hen 7/8 cock
Fourth Generation Hen to grandson Cock to granddaughter 15/16 hen 15/16 cock
Now in the 5th generation you breed the 15/16 hen to the 15/16 cock. Then, choosing the best hen(s) and cock(s) you begin again (Narragansett, The Gamecock, 1985, pp. 44-45).
C. A. Finsterbusch recommends the same breeding strategy in his famous book Cockfighting All Over the World page 152—153. If they chose to continue line breeding these fowl were what they termed “seed stock.” Seed stock was never pitted. Instead, they were crossed to a different strain to produce their “battle cocks.” Battle cocks were never used in breeding pens if this system were employed.
......

If you replace \"battle cocks\" with \"show birds\" you could see how this could be applied to Ameraucanas.

If anyone is interested I can email a Breeding Chart to you.  It is by Gene Gilbert and was featured in GAMECOCK years ago.  I don\'t use the system, but it may be of interest.  I\'ve shared it with Paul and others in the past.
I do believe that unless you want to introduce a trait that your birds don\'t have you can breed from a closed flock without needing to introduce new blood.  Inbreeding can cause problems, but by maintaining two or more stains of each variety you can avoid them.
Sometimes those that buy chicks from me are concerned about breeding them together, since some could be full siblings and they\'ve heard about the horrors of inbreeding.  I recommend they don\'t worry about it that first year.  Setup at least two matings of the best, keeping \"compensation mating\" in mind.
The following year breed the males from pen 1 to the females from pen 2 and vise versa.  The other alternative is to breed sire over daughters and/or sons over dams if needed.

CAN I GET EMAILED THE BREEDING CHART? Thank you. Bonnie
