I am not really keen on barred chickens but when I saw black and white barred NN I decided if I ever find one I must have it. I think it is their neck that interrupt the boring pattern (boring is my personal opinion, no offense). if there are other colours together with barred I like it. I have a pullet who has patches of buff and patches of black and white barred. her name is bella (beautiful in italian) - just to explain how much I like her.
