I have a quick question. We have a pair of gouldians on a nest. The male is RH/WB double Factor YB and the hen is YH/WB/GB not sure if she is split to blue. When we go to the gouldian genetic calculator and put in a RH/WB/YB (double Factor) male and cross him with a YH/WB/GB split to blue hen, it magically tells us that all the hens will all be green instead of yellow like they would turn out without the split to blue part of the mothers genetics. Does being split to blue affect back coloring or is this a mistake on the calculator? I cannot for the life of me understand why it would give us this outcome based on the Breast color of our parents. Any help would be great

Thanks

All the male chicks will be SF Pastel AKA SF Yellow and all the hens will be Yellow. I have no idea why the calculator isn't saying that. Also some males and some hens will be split to Blue

Which calculator are you using?

Yeah I thought it was weird to. I'm using the following:

Yup, definitely something wrong with that calculation combination very strange
