I have two lavender orpingtons and I have done some research on the breeding of them. I understand that a lavender to lavender makes more lavneders. Lavender to split black makes 50/50, lavender bred to non-split black makes 100% split black and so on. What I don't understand is why blacks are bred to the lavenders. I am thinking that they help with the type, yes? I am wondering if this is needs to be done when breeding lavenders? Thanks.
