RE: Calico Buck
Did you not read it? Apparently you just looked at the pics huh? It's not called a "Calico" but is called a piebald deer. Uncommon but more common than a white, albino or melanistic (black) deer.
I hunted a piebald doe exclusively one season, had her at 50 yards 5 times (bow only) and never saw her again.
I've seen several.
Good Luck and Good Shooting
