Can someone please help me to figure out if my 18 week old Blue Silkie is a hen or a rooster? I am really hoping that it is a hen. She is such a sweetheart and on the timid side, lower on the pecking order. She always comes right up to me when I am around and loves to be pet. :) I have had 4 silkies and the other 3 turned out to be roosters.
