I can't verify whether the above info is perfect in regard to the outcome on the colors because lacing makes me want to scream into the night. I was shocked to see a Golden-laced Orpington chick hatch out of my visual Silver-laced pair. I do know that splits will be produced. Also crossing Blue-laced Red to Gold-laced results in the loss of the mahagony gene, or at least that is my understanding. So your offspring will not be Blue/Splash/Black-laced Red but instead will be Blue/Splash/Black-laced Gold. I'm not sure over how many generations it takes for the color to lighten, but I do know that it happens.
