My roos get along pretty well, but they do fight alot. And some times they all chase one of the other roos and, he gets so depressed... But other than that, they are fine together.
The second one from the top is a pullet. All of the others look like cockerels. I'm no expert though. I have forteen White Silkies and all of them have five toes exept for two, one of those two has six toes and the other has five toes on one foot and four toes on the other.
