There are four species of Gallus. Only one, the red jungle fowl hens, became the mother of modern chicken, in several places at the same time, but the history is more complicated than that.
Indonesian for example have an endemic species, the green one, and are fond of producing red+green hybrids for navigation at open sea [1]. Green is the oldest species and does not live in China.
Then we have the chicken skin. Plucked chicken are typically yellow. Only a few chicken breeds have black skin, they are all black in fact, black beak, legs, caruncles, crest, inner organs and even black bones
But when we think in a plucked modern chicken is yellow. This is because the grey species, from India, provided the yellow gene. Therefore all (or almost) chicken that you can buy in the market have indian blood. Grey (and Ceylon's wildfowl) are endemic from Indian continent. And any study that is not sampling this areas would be incomplete.
The red was adapted to rainforest but is a species from bamboo cloud forests also in the mountains, so provided the cold resistance gene, and won in the battle being the easiest to breed.
[1] Each rooster has a different song that is really loud and unique from this animal. People go fishing with their pet rooster and thus can locate the position of all other people easily even in dense fog or open sea.
Yes but this couldn't be done with the red. The green junglefowl is a mangrove species, so was particularly well suited for the fishermen lifestyle. It feeds on fishes, starfishes and marine animal's carcasses stranded in beaches and can survive without drinking freshwater for a longer time. Is perfect for long distance open sea travel and to colonize small isolate islands without permanent sources of freshwater
Araucanas, ameraucanas and olive eggers have its blood. It provided the genes for blue and green eggs.
