As I have heard, dominant white is the exception to the norm in Silkies. I have a paint too, in her background I was told was a leghorn that introduced the dominant white to a flock of black silkies. I stand corrected, I agree I should call a chicken a pure breed, but what I mean by that is that if someone is working on breeding Silkies, especially for show, they will be culling out traits, or genes, that are not true to the Silkie standard. I think after quite a few generations it is safe to say that those silkies do not carry genes that would label them as anything but Silkies. Though I will say there could be that lucky little recessive gene that can hang on for generations and generations then pop up very unwelcomed.As I was told, there is no "pure breed" chickens and I have a paint silkie currently. That is black with one copy of the dominant white gene. Her name is nugget. MOST of the time hatchery silkies are recessive white and it is difficult to find a dominant white silkie but folks have been working on them for a few years now. Silkies do in fact come in dominant white. The only way to know for sure what you have is to do a test breeding to a black bird and see what pops up. That's if you don't know the birds history. Thank you.

Test breeding must be done with more than just one bird, I have a blue hen that carries recessive white, I bred her to my white rooster (who is hiding splash) to work on type in my blue pen and wound up with 3 white chicks. After asking the breeder she came from I was told she could definitely be a carrier of white. If I hadn't asked I could have though Snowman was dominant white, but he is not.
Unless the Silkie is a paint, I always assume it is recessive white. Just from what I have been told, dominant white silkies are pretty rare, and (I would hope) the breeder of one will always share that information to a buyer/breeder.
