Do a search on here for "Walnut Comb" to see what it looks like. Or, go to the Silkie thread and someone will post a pic for you. The other poster was correct, Silkies should only have Walnut combs, not single combs. The comb color on the Silkies should be a "mulberry" to black too, not red. Here is the link to the Silkie thread (one of them!) https://www.backyardchickens.com/t/297632/silkie-thread/20900
