Just noticed that my silkie roo looks different from the other roo my grandmas friend has HE HAS A SINGLE COMB NOT A WALNUT COMB!! Well on to the question about breeding I'm breeding him to some Wyandottes and some silkies this spring and someone said that the Feathered leg, Crested, and 5 toe genes are dominant....is the single comb too? I want my Wyandotte chicks to keep their rose comb gene since its pretty cold here in utah.
