Along the same lines, I\'m having issues with my juvenile blacks having faint traces of white across the tips of their feathers, mostly in the lower back. Didn\'t notice it last year (only hatched a handful, though) but the one cock that I kept has no trace of white that I can see, so not sure if this will go away, but since I\'ve also had a big problem with super-slow feathering in the blacks I\'m wondering if this is the barring gene and if so, where I go from here, since they\'re all closely related.
