I would breed him to the black and the 'white' hen. From that group, if the white is what I believe her to be, all of her offspring will be Blue Paint, whilst all of the Black hen's offspring will be Blue. I wouldn't put the partridge hen in, as that would involve mixing the e-series; the three other birds are (or ought to be) based on Extended Black, therefore any offspring they have should be pure for their colour variety. When you mix the e-series, the offspring will all be impure; blue with gold/silver leaking through, depending on the father's hidden ground-colour.
