Breeding Question

[16Chickens Keeper]

So how would you breed for feathered feet and 5 toes? obviously, you'd need a Sultan, Silkie, etc.
But how many generations until they breed true?

I had most of my chicks with various hens and one Silkie rooster come out with 5 toes in the first batch I incubated.
