BYC Genetic/Breed Calculator Huge Task Ahead!

But they are spangled and mottled right? Red, black and white?

The Spangled Sussex is not genetically spangled, the Spangled OEG are not genetically spangled, they are just mottled birds.

On Wheaten e^wh and Dark brown Db you get gold unicolor as a possibility. I would like to see that color in real life for myself.
Unsurprisingly the opposite of this is silver unicolor, which looks basically white. It has sexlinking potential I s'pose.

e+,eWh,eb, ey males with Db/Db(dark brown) columbian restrictor will have a Black Tail buff/Silver(s+/s+ or S/S) phenotype on non red enhanced or diluted birds, while is very unlikely to find Db alone on a single bird(due to the close linkage to the pattern gene), Pg has no effect on males making Db/Db Pg/Pg males look like pure Db/Db males.

a few examples.

White Tail Red(eb Db/Db Pg/Pg)

Ok. How do the black spots appear then?

The calculator should include the possible size of your a bird and if your chicken has any genetic defects you should be to include that into factoring how the offspring will turn out. This way you can see if the genetic defects will be passed on or not.

While Mottling on an all black background will look like just white dots, the feather pattern will show both black and white dotes(on the same feather) on none black diluted(dominant white/Blue) background.

The effect on some background may look tricolor. For more info: http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.1006.5209&rep=rep1&type=pdf

Oh. Cool. I didn't know that. How interesting. Is Mille Fluer just mottled then?
ETA: I looked at the calculator and it looks like it.

I think this would be too complicated to figure out. Especially size. There are no known (at least by me) genes for size. Plus measuring size sounds hard to do as well as other things that I don't want to explain. And "very small" would be different to different people.

Yes, mille fleur d'uccle bantams are just mottled, but I am sure they are bred for good pattern.

The Silver Mille Fleur really look like Silver Spangled, but you can tell they are mottled due to the lack of a "Tear Shaped" black spots and the white end on the tip of the feathers

They are very cute.
