I don't know what kind of birds you are working with but here is what you would need to build the Mille Fleurs and Porcelain pattern.
e wh -- wheaten down color. Wheaten/whitish colored female. Male Red/Silver hackle and saddle, with a black breast.
s -- sex link gold, we want a red bird, not a white/silver one. Now we have a Gold Wheaten instead of a Silver Wheaten.
Co -- columbian Removes the black from the breast of the male. Now we have a Buff Columbian. Makes males and females the same color.
mo -- mottled. recessive 2 genes required. This adds the black bar and white dot. to the end of the feather. Now we have a Mille Fleur!!!
**If you add one gene of Bl you will have a Blue Mille Fleur. If we add 2 genes you will have a Golden Neck.**
**Take the same Mile Fleur that you just built. If lav -- lavender is added in 2 doses (it's recessive) you will have a Porcelain.**
