A lot of people confuse Red Sex-Links with Rhode Island Reds,but they should not be confused. Sex-Links have chararistically white-striped hackles and white tail feathers,Rhode Island Reds should not have any white feathers in their plumage if they are true to type. if your so called 'Rhode Island Reds' have any white on their plumage,they are definitely not Rhode Island Reds.
