Quote: Stan, I think what you are going to do is use one of the Blue Roos from your original cross is that right? So if you cross the Sex linked roo x blue you will get 25% barred pullets, 25% Barred Roo (again sex link with only one copy) and 25% Solid Pullets and 25% Solid Roos, The barring will be harder to see on the splash barred roos. I don't have yellow legs in my Blues, working on it but having to do it through the back door, I don't think it is going to be easy. As for egg laying you will just have to be diligent and only hatch eggs from your best layers since they will have a mix of GSBR genes too.
Leg color is just a big problem in the blues. I have a splash maybe 2 I can't tell for sure both have lighter legs, but not the chicks from them. Something must be in the blue genes to hide the leg color. I have lots of hatching to do to get lighter legs......
