A white & grey coloring scheme is somewhat rare
especially in the Eastern Sub-species of the wild
turkey. Would definately make a fine trophy mount.
It is somewhat more common in the Merriman sub-
species that are found more in Texas & New Mexico.
Some biologist say this is the albino trait found
in some species of the wild turkey. Hope this helps
a little. I would be after them like a mad-man
come spring. Also you did not say what state you
saw these in. Good luck God Bless
