And would it jut be easier to breed her to a porcelain D’Uccles rather than fawn?
As regards color genetics, that would be much easier.
Which mating is better would depend on what results you want in the chicks: pure for OEGB traits but mixed for color, or pure for color but mixed for OEGB and d'Uccle traits.
@NatJ i am going to breed my porcelain OEGB hen to my Fawn OEGB so I can continue the porcelain color, a cording to the calculator I’ll get this
What does all this mean? I know the chicks will be recessive lavender and recessive mottled
Yes, the chicks should all carry mottling and lavender (recessive genes) but without showing those traits.
Taking the rest in a slightly different order than you listed it:
These pullets are the easiest.25% Pullets, black patterned silver incomplete-columbian
They look mostly Silver Columbian, probably with bits of black in some extra places.
They inherited the Silver from the Khaki OEGB father, and the Columbian gene from the Porcelain d'Uccle mother.
The Khaki OEGB would have e+ wildtype/duckwing at the e-locus, and a Porcelain d'Uccle should have E^Wh Wheaten, but I do not know what the Porcelain OEGB has. They may have e+ or E^Wh or some of each (because they were probably developed by crossing Porcelain d'Uccles with OEGB, and either e-locus gene can work to give more-or-less correct Porcelain coloring.)
So the chicks might be pure e+/e+ wildtype at the e-locus, or they might be E^Wh/e+, or there might be some each way. You might or might not be able to tell by looking at the colors of the chick down.
Just like their sisters (described above), except that these pullets inherited the gene for fawn/dun from their father, so all their "black" areas are fawn-colored instead.25% Pullets, fawn/dun patterned silver incomplete-columbian
The cockerels will mostly look like their sisters (some with black, some with fawn/dun)25% Cockerels, fawn/dun patterned yellow/golden*S columbian
25% Cockerels, black patterned yellow/golden*S columbian
*S = heterozygous Silver S/s+
What does all this mean? I know the chicks will be recessive lavender and recessive mottled

But on the cockerels, as they grow up, the "silver" will probably look a bit yellowish (because they inherited the gold gene from their Porcelain OEGB mother, in addition to the Silver gene from their Khaki OEGB father.)
