Well, I had forgotten completely about toes. What's that disease I can never remember.... CRS! Also forgot about the comb. Silkies have a pea comb ( looks sort of bumpy). I bet Red has a Cochin. If the comb is a regular, classic style single comb, then the new hen is probably a Cochin. Super sweet, excellent broody, maybe not the smartest . Pea combs are dominant, so that would carry through from a Silkie cross. Is she round shaped, Red? Sort of like a feathered ball? Short little rounded off tail? round one in the center behind the post is Cochin. (the fox got her ). Hairy one in foreground is silkied Serama. (She's my sick one now. ) One thing I have found is that most people who are not on BYC are less knowledgeable about poultry in general. If someone gave them some birds and called them Silkies, that person doesn't know any different and goes on calling them that, so it happens. You can tell a hard core breeder because they care mostly about the shape of the bird. If it has the wrong shape, it is not considered an example of the breed. The color is secondary. Most of the mass produced hatchery birds are nothing like their breed is supposed to be. They are still good chickens, especially if you want eggs, but they would be immediately disqualified from any show. The Standard of Perfection is the book that describes how the breeds should ideally look. Some breeds, like Cochins, have been around for over 100 years! They were sort of bred to be the chicken equivalent of a lap dog.
