My silkie roo is purebred right? He was sold to me as a purebred silkie. He has the black skin and the five toes but he has a red comb? Could he be mixed or somthing eles and if somthing eles what would have caused him to have the red comb? I have chicks from this roo and all the chicks that have turned out to be roos have the dark mulberry comb. Here is a picture of him oh and what type of comb does he have? Also is it possible if I bred him that sooner or later a roo chick may turn up with the red comb as well?
