I don't know, they are either girls or boys. The blue I would definitely go with girl. The splashes don't really look definitely boyish or girlish. Maybe some comb pics will help.
They might if they had anything, but they dont. They have barely changes since little babies. That why i am still hoping girls. The biggest sign for me is the tails. They look all roo-like on at least 2 of the splash's. But could a boy this old have no comb or waddles yet?
I would think you'd start to see a comb if they were boys by now. Can't really rely on wattles in Silkies since most bearded Silkies have but a smidgen of wattle. I would go with ladies.
