Hi. I am new to chickens and currently have six. They are about five weeks old. They were purchased from TSC. Two were labeled brown pullets, two were labeled red pullets and two were Black Sex linked. From all my reading and researching I do believe one of my Black Sex links is a Roo. He is barred and has a larger comb than the other five. I also have two Pekin ducks and three Rouen ducks (used to have four, darn racoons). I love this forum very informative and wonderful people.
