I have 3 silkie chicks. They are approximately 10+ weeks old. One has started crowing. The other two appear to be females. Of course, that will be seen in the future. The two females (thinking they are based on crown development and body language) have started sparring today. The smallest one is the instigator. That is the one I would put money on being a female. Has anyone had experience with female chicks sparring? Just curious. Thanks for any replies.
