The color variety of the SELF BLUE breeds does reproduce true to a blue color. However, the regular blue color varieties reproduce generally offspring of 1/3 blue, 1/3 splash and 1/3 dark blue. This is a genetic anomaly that occurs with the blue feather coloring gene. You can breed splash to splash and that will produce 100% splash. You can breed the splash to the dark blue and this will produce 50% blue offspring. Our breeds of blue currently include blue Sumatra, blue cochin standard and bantam size, blue old English standard and bantam size, blue polish, blue rose comb, blue slate turkey and Blue Swedish ducks. Our breeds of SELF blue currently include self blue old English bantam.
