Are there any literature, website, or topics on HOW to sex a silkie? For example, are there any particular traits or features? I have seen experts do a great job. So there are characteristics to make a good guess? I already know that "if it crows, it is a rooster" and "if it lays an egg, it is hen." This is blindingly obvious. I ask this because I love silkies, and I simply want to better my education of them. Information that has drawings or pictures would be nice A description is fine, too. This is just a request for information.
