UPDATE: Splash silkie is a hen. She laid her first egg a few days ago. Black maybe roo? I think he mated with her? He mounted her by grabbing on her neck feathers with his beak. So I think he is a roo. So I have 2 two month old silkies that im kinda sure what they are but need reassurrance. The gray and white (splash?) is a roo and the black is a pullet. What do you think? Also when will they get all there fluff?
