The odds of her being a Sultan X are very slim since they are so rare. Thats what I get for not reading LOL
I just saw that the bottom bird is not the top bird. She would WAY more feathered feet even though she is a cross, Sultans have Vulture Hocks which would produce normal looking foot feathering in a cross and not a few feathers. I would say she is a Polish X Langshan
