Gray is technically the same as silver partridge.
Hmm, my black silkie chick is quite a bit darker than Oreo. Maybe just variance in the color?
Your question is not stupid, genetics are confusing. You will most likely get blue or black babies. Hard to know what your white silkie is "hiding" underneath the white. If there is blue, then splash would be possible. You would have to breed them and see! Many recessive whites also carry partridge, so a variation of this can pop up as well.So from what I understand, if Oreo is blue and I have a white silkie, (which I do), depending on the white silkies recessive color I could get splash babies? If this sounds stupid sorry!! I'm SUPER new to the whole color genetics thing.
