    I am trying to get a better understanding of the genes required to make a sex link with a RIR roo. ( I know not all White Rock hens will work since some do not have the silver factor gene.) My preference was to use a Light Sussex or Delaware hen which I believe should work 100% of the time?

    RIR X Delaware = Red sex link. Would the Lt Sussex produce a red sex link too?

    Could you use a Coronation Sussex hen?

    Yes, all three of those breeds of hens can be used for red sex links.

    Thanks for the confirmation!

    Can someone explain why some 100% of some breeds can be used vs. other breeds like the Roc needing the "silver factor"? Is it simply a dominant white vs. recessive white gene?

    Are there any sticky threads that explain the silver factor? Haven't had luck finding one.
