And human nature being what it is; anybody 'out there' who may happen to have one, would see it as your duty to sell your bird to him . . Just as you would see it in reverse.
And . . if he has a breeding programme in train, he may well be right
Which puts you 'on the spot', in that you will have to start with 'colour' x 'normal' = all 'splits' . . A long road; but an exciting one

And . . if you do happen to get a pied hen . . it may be a different 'pied' from yours, and you will then get young that are normal looking 'double-splits' . . for some added excitement
Can you still feel that "sense of responsibility" . . ?
