I went digging and came up with a few pics. The first is a splash wheaten cockerel (Barbara Campbell). Note it has the same pattern as a wheaten and blue wheaten, but the feathers that would be black on wheaten and blue on a blue wheaten are \"splash\" on a splash wheaten.
The next two are of a young splash cockerel. Others may be better at describing this variety, but it is basically a white bird with \"splashes\" of blue here and there.
Another topic is discussing shank/leg color. Note that the shanks are darker on the splash bird than on the splash wheaten. It is common for varieties that are recessive wheaten (buff, wheaten, blue wheaten, splash wheaten) at the E-locus to have lighter slate shanks than those that are wild type (silver), extended black (black, blue, splash) and birchen (brown red). We are still striving for as dark a slate shank color on the varieties that are based on recessive wheaten as is practical.
