Hello Jason, and welcome. Dominant and recessive and incomplete dominance only have meaning when applied to specific traits. A single bird may have both dominant and recessive traits. Concerning wheaten and blue-wheaten, a single gene (Bl) dilutes black to a shade of gray which in chicken talk we call blue. One copy of Bl added to wheaten makes blue wheaten. Two copies of Bl make splash wheaten. Splash wheaten crossed with wheaten should yield 100 percent blue wheaten progeny. Splash wheaten crossed with blue wheaten should yield about 50 percent of each of the two colors, but no wheaten. Splash wheaten is not a recognized color, perhaps because in the eyes of many the males are not very attractive. But they can be very useful if you plan to produce or sell blue wheaten chicks. The three colors are not distinguishable by the color of their chick down.
