I think that is (possibly) what the problem with the Delawares is now - too many strains all mixed up together. One strain has green legs, another strain has horrible pinched tails, etc.... Folks have crossed these and now many of them have all those bad traits. From what the old timers say, I think it is best to stick to one strain and keep working with the best ones hatched each generation.if you can get the 3 pullets and the cockerel, then i would start there with what you have. add some other strains like birds from whitmore farms, beth holmes, sandhill preservation and paul harter. hatch, breed and cull ruthlessly. i would wait until kathy in mo had a finished product before getting them and maybe only a rooster then.
