Sexing silkies

[FancyChicks2]

Ok. I’ve read everything I can find on this subject and need opinions of other more experienced silkie raisers. Can you tell me if these are make or female.(they are about 10-12 weeks old) My tiny one has some feathers coming off her top.
So I am guessing male which is weird because he/she is small. The other one I can’t tell. The pink one is the small one and the blue is larger but they are the same age. Thanks!

I’m not sure. Silkies are hard to tell. I have three almost 5 month old silkies. pictured below. I think the one on right is a girl. Looks like momma. Not sure about middle and left. But in the mornings when my mature Silkie roo comes out of coop and they are still inside, someone is crowing inside. Haven’t caught the culprit yet
