I'd like to cross a Black Cayuga and Khaki Campbell to make some sex-link ducklings and had some questions about the genetics involved. If I have a black drake cross that came from a black male and chocolate female cross, then cross that black drake to Campbell hens, would I still have sex-linked offspring or would the chocolate genes the father carries get in the way of that? What I'd like to do is the following: black drake (black x chocolate cross) on a chocolate hen. The end result is to be able to immediately separate out broilers and egg layers without having to wait. Thanks.
