Ok, so reading The Game Fowl Breeders Manual Vol.1 by Mr. Troiano. In one of the sections he states that one could create two lines of fowl just from one cock and one hen with the result of the line from the cock side and one from the hen. Now I understand how this works, my question is can this be done with three birds of different blood? One cock of one blood, a hen of another, and yet another hen of another, or would this be to difficult to keep track of? Keep in mind all three birds will be used to create one consistent line of fowl, your own.
