Hi PAUL, The best mating for grizzle is blue bar to grizzle. Grizzle is an autosomal dominant which produces variable depigmentation in feather color., so never mate grizzle to grizzle as the young from this mating will result in white or near white birds.In grizzles, the clumped pigment areas, because of increased spacing, are lighter then spread areas.So for this reason, checker and T- pattern grizzles show less expression of grizzle,and are not nearly as attractive as bar. GEORGEI guess the bigger question is, What are the rules to mating in regards to color?
1. Specifically if I mate a grizzle with a typical BB pigeon or a Recessive red pigeon. How does grizzle affect each.
