Your wings look good on the rooster. We had some almost solid white feathers show up in some of our roosters. If you have one of these feathers in a male or female pull it out and 8-10 weeks later a new feather will grown in it's place and sometimes change color to what you want. I like the body type of the rooster in the photo and just the way he carries himself. I just can't see how big he is but he looks good and I'm sure a lot of people would like to own him
I've heard that before about pulling the feathers but never tried it. I have noticed with some of my older birds that sometimes they moult into decent colour--but sometimes they grow a white feather out of the blue. I guess I don't really have a reason to pull it unless I wanted to show them.
