No, that is not true, the only way you can get BLR is by breeding BLR. If the bird was silver laced as in splash laced and you crossed it to a golden laced, you would get blue laced golds. The gene for gold and red(mahogany) are different things. If you want BLR, just buy some from a good breeder. Also the polish egg will more than likely be a bird that is buff laced looking with some black, I think, depends on what parent was what color.
