In D'Uccles, Can you tell the difference between citron, lemon and silver as 2 1/2 week old chicks? If so, how? I have 2 that have hatched and they are much lighter than than my Mille Fleurs and gold necks. They are not porcelain or white. I could take some pics but they would not be really good ones. If I could just know the differences to look for.
