Yep, but I probably shouldn't have posted yet. Repeated some crosses with eggs in the incubator will know more in a couple of weeks. Using this guy for some. He's out of a Bielefelder male and Light Sussex hen so he's split nine ways to Sunday e/eWh, co/Co, Mh/mh, s/S ,B/b, and may not be...
Based on a recent cross that I made I'm beginning to think either Bielefelder of Light Sussex have some kind of hidden black that is suppressed in the pure birds. I'll post if I can confirm. I can say that Light Sussex are homozygous for the autosomal red inhibitor Aph^I.
I'll post if I learn...
