A purple hen bred to an India Blue or a IBPied will produce all blue hens and blue males split to purple, If it is the pied male the birds should be split to pied. On the sex link colors it is the male that makes the difference in what you get. ,,,.good luck.. George
He means that in theory you should get half visually Purple sons and half that are IB split to Purple. Of the daughters you will get half that are Purple and half that are IB. Of course this never works out exactly as it does on paper, eggs get broken, eggs quit developing, chicks fail to hatch, all of these variables will make the actual results different from the "in theory" results.
