I ordered some of these from idealpoultry in texas. One of my roosters and one of my hens have single combs. Does anybody know of a breed that looks like the Silver Laced Wyandotte and has a single comb? Or did i just get a hen and rooster with a genetic defect? The look absolutely like Silver Laced Wyandottes except for the comb. If i do have a couple of sports as i think they are referred to could i not use them to start a line of single combed silver laced birds?
