I'm curious as to how common this is. I have a poult that's about 3 months old, and he's really turning out to be a real beauty. He's mottled black and has deep gray-blue eyes. I know he's a product of one of my blue slates, who I've noticed have a ring of the same blue around the brown iris. I also once had a poult hatch with one blue and one brown eye, but unfortunately, it didn't survive. All my other turkeys have either black or brown eyes. Is my guy just one of those rare occurances, or are blue eyes fairly common among domesticated flocks?
