He could be, I honestly know nothing about genetics/colors.Beautiful! But isn't he millie fleur? Calico looks more like the hen in the pic (the very white one with buffish spots) or @HappyClucker7's Cochin Mamgo
You'd know better than me.
Edit: He sure does look like the Mille Fleur's on google. Thanks for bringing this to my attention, I had no idea.
