Jerry,
Where did you get the barring gene from?
I have a couple of Cuckoo projects going , one being Lavendar Orps and have been wondering what I should use to get the barring gene?
Well I am also doing lavender cuckoo orp .The barring gene came from 3 different breeds that were eventually combined . I tinker a lot just to see what I get . White leghorn carried the first . I was making super blue layers at that time . The next was Araucana that carried barring and Erminett . Last was barred rock . I would suggest barred rock or maybe work together .
