Lavender and chocolate splits genetics question

[Ivy_Chickens]

Okay, so I ran into a question that stumped me. I wanted to breed some splits for my chocolates and my lavender orpington flocks, and thought I'd be clever and instead of putting a black orpington in with them, I'd just mix the lavender and chocolates. It made sense in my mind. Both genes are recessive and both work on a black base, so I figured a chocolate rooster over a lavender hen should give me a few chocolate pullets split for lavender and a few black roosters split for lavender. So I get two splits in the same pen. But then I became stumped. What happens if you breed two splits that carry both the lavender and the chocolate gene? For example, if I breed a chocolate roo to a lavender hen, he should give me chocolate pullets split for lavender and black cockerals split for chocolate and lavender. If I breed those splits together, some of them should get a lavender and chocolate gene, which to my mind means some sort of double dilution similar to mauve? This is confusing me because mauve is blue or a splash mixed with chocolate. These are all dilute genes, so what am I missing?

The lavender dilution is way stronger than the chocolate. A lavender and chocolate bird looks basically lavender. I’ve never done it myself but you could expect a very slight difference between black+lavender and chocolate+lavender.
I’m going to run it through the calculator rather than listing all the genotypes you’d get by crossing the splits.

Here’s the punnet square of the split lav chocolate gen cross double split cock.

Edit: see how both choc/choc and Choc/choc lavender cocks are lavender
