I created these myself . You need barring and chipmunk striped chicks . Crele is the color .There is Legbar in the mix . Legbar are auto sexing . You must have males with 2 barring genes . I had started work on crele EE but only had a rooster with 1 barring gene . So to save a year I used a Legbar rooster last year . These will now breed true for auto sexing I will include a picture of the crele mix breed rooster I started with .
