I finally got some updated pics of the silkies. Turns out the white and darker grey are the females and the lighter grey and brown are males. These pictures were taken about 2 weeks ago. They have even developed more since then. The grey male has since developed one really long brown streamer which looks pretty cool and really sticks out. I'm gonna try to get a picture of that tomorrow as well as a video of all of them. And the Easter Egger has now started laying one egg per day...yay!
Can't wait till the 2 female silkies start laying also. I think we are going to keep all of them despite their gender.
