G'day, Can anyone help me with this question ? My Rhode Island rooster is a prime example but when he extends his wings he has a white feather or 2 in each wing tip that is not obvious unless he stretches. Is this acceptable for a show quality bird, is this common in this breed ? I also have a pullet that has some black in the back of the neck, both have black in the tail. I would be grateful and appriciate your advice and knowledge ! Greetings from Down under !
