It's possible one is a little older than the other. The dark grey one had a straight comb so it's hard to see.. Also are there different varieties or is a silkies just a silkie?

Can't tell from photos, either they are facing away or to the side or down not toward the camera. still young to sexing a silkie 4-5 mos. of better and sometime snot till they lay or crow.

It's too hard to tell by the pictures.
