SOME WONDER HOW CERTAIN COCKER-breeders produce outstanding fighting cocks without any knowledge of gamefowl breeding basics. Others do well in game-fowl breeding loaded with all breeding methods found in the book. The former succeed due to their innate talent or "feel" of the gamefowls, while the latter reach breeding goals due to education. Those whom the author have seen attain breeding goals in so short a time, have that "feel" of the gamecock and read a lot of books and magazines pertaining to gamefowls. It is with this thought that the author decided to touch on this subject?
There are lots of breeding theories found in the book, but the two most famous are inbreeding and cross-breeding. Let us first touch on inbreeding, Inbreeding is the mating of closely related fowls. If you want to know how to inbreed gamefowls, Iook at the percentage of inbreeding below.
1. Mating brother & sister- 25% (intensive inbreeding). 2. Mating half-brother & half-sister- 12.5% (moderate inbreeding). 3. Mating uncle & niece; aunt & nephew -12.5% (moderate inbreeding). 4. Mating grandparent & grandchild 12.5% (moderate inbreeding). 5. Mating first cousins - 6.3% (mild inbreeding).
Select the percentage of inbreeding you think will be applicable to your gamefowls. Remember that the purpose of inbreeding is to fix like genes. The more you inbreed; the more like genes are fixed. These will be further boosted by inbreeding birds having the same phenotype characters tied to some genotypes.
When you inbreed fowls, watch out for atavism. Atavism is the recurrence in a descendant of characters of a remote ancestor. It may result in deformed beaks, eyes with irregular pupils, breast defects, crooked toes and backs, etc. Atavism will also result in phenotype throwbacks - especially plummage phenotypes. Throwbacks are homozygous dominant.
A friend of mine once bred a pair of Ray Hoskins Grey. Out of this pair of Grey fowls - two of the progeny were Whites. This pair of White throwbacks begot outstanding cocks - all Whites. He also crossed the throwbacks on other Whites of different strain and still come up with winners. The cross of the White throwback with mongrel cocks also produced good pit fowls. When atavism results in color throwbacks, check if the color phenotype is tied with fighting prowess genotype. When bred, it will give positive results. Genetics is a very tricky business and does not always follow prescribed rules designated by us. Most breeders maintain highly inbred strain of fowls as seed fowls. These breeders do not fight broodfowls; they only fight battlefowls.
