Therre is no official silver. Could they mean self-blue?So, I have a question. I was planning on adding a D'Uccle to my flock and I wanted Porcelain. The breeder who is finding me one is having trouble finding Porcealin, but says she can get me Silver? Aren't there different kinds of silver in D'Uccles? Is it a registered color? Does anyone have pics of silvers?
