It fights with my Golden Sebright rooster and doesn't lay any eggs. Also when it was my only chicken it would make a little sqwak in the morning but it didn't sound like "Cock-a-doodle-doo!" Also it doesn't have any spurs.
its a boss hen, i got a silkie hen like yours. She'll beat anybody and she does lay eggs, but I have never gotten a fertilized egg from her. How old is yours?
