It has been claimed that the Cornish X is... a MONSTER or a MUTANT or a GENETICALLY ENGINEERED ORGANISM or a FREEK and a few other claims. Now, it may be possible for a natural gene mutation as this occurs in Nature from time to time and is the basis of evolution of new species. It is also possible that someone recognized the new gene mutation and saw the benefit gained by selectively breeding the new mutated bird with selected other lines of chickens. Or, it may be a group of dedicated scientists that spent decades of selectivey mating lines of superior meat producers and crossbreeding them to achieve superior results of producing the most meat in the shortest time possible. If anyone has scientific proof of gene modification with another organism by a human , PROOVE IT !!!
