Crowing
Pretty sure there are exhibition and production rouens. Exhibition being larger like what you are wanting. My rouens' bodies look just like yours. Pretty sure they are plain old production ones. Any experts feel free to correct me if I'm wrong.
Yes. Exhibition Rouens are used for showing and meat- they have very large keels and are block-shaped, standing almost horizontally. They lay 35-125 eggs per year, and are 8.5-10 lbs.
Production Rouens lay 100-180 eggs per year, and are shaped more like wild Mallards. They are 6.5-8.5 lbs.
