I have kept chickens for years but I have never messed to deeply in the genetics side of it all. I recently obtained 2 Barred Plymouth Rock Pullets. What will it take to have sex-linked offspring from these girls? I also have a few sex-link hatching eggs coming in a couple days. So I may have a couple of each sex out of those. This genetic stuff can get pretty confusing so any help made simple would be much appreciated.
