Jean, it might be possible that dominant white came over from the buff side of the mating. Dominant white is sometimes carried in buffs, as it tends to lighten the color. If I\'m not mistaken, John used buff polish at one point, which I believe have dominant white. Are any of your buff birds descendents of his line? By the way, most buffs are wheaten based (e-locus) so it is possible to produce wheatens out of certain crosses with buffs. Coincidentally, I crossed buff with blue wheaten bantams this year, and some of the F-1 look like almost pure buff.
