Genetic science behind partridge and buff silkies

[Jessie404]

Hi all,

I have recently bought my first silkies, I have 5 black, 2 white and 1 splash, unknown genders but according to breeders guesstimate 1 black roo and 1 white roo. They also informed me that I could get a blue from crossing the black with the splash. After learning this I was a) wondering how the partridge and buff Silkie came about, since they are so different in colour, and b) wondering how you can make a partridge or buff coloured Silkie.
Also, if anyone could do one of those genetic breakdown with colour and what creates what that would be really helpful too.

To create partridge or buff silkies from scratch you would have to cross in other breeds with those color varieties.

This page talks about black, blue, and splash:

White is genetically complicated. There are at least three different genes that COULD make a white bird, and quite a few others that could also be involved, and they all behave differently.

If you want nice white Silkies, only breed them to other white Silkies, unless the breeder told you something different. (Because the breeder knows a lot more about YOUR birds and their genetics than I do.)

But if you just want to see chickens of unexpected colors--you could breed a white Silkie to one of the other colors, then breed brother & sister among the offspring. I cannot predict what colors you will get, except that they will probably not be a recognized color that can be entered in poultry shows.

If you specifically want partridge or buff Silkies, it is far faster to buy some than to try to develop them yourself. (The necessary genes are probably not present in the Silkies you have.)
