County Fair is coming up soon and I want to show my Barred Rock Rooster. He is gorgeous. But I noticed today that his cape and some of his side feathers, if the light hits it a certain way, seem to have a cream/yellowish tint to them. Reminds me of gray hair getting that 'yellow' tint. How do I treat this and will this be interpreted as a hybrid bird; he is full bred. What is Blue Ribbon shampoo and where can I get it? Can I use something else? I live in Florida. Thanks.
