Yes, there are lesser pieds that are not all white. I saw that same one at Tinley this weekend and I've got another picture of it around here somewhere (Adam was nice enough to take it out for me and let me hold it) I understand that Pete has hatched others like that. It may be that the 'norm' is for small patches of color and the 'all white' condition to be more uncommon. There really aren't a whole lot out there yet to really make a determination on what is typical.
