Both parents for Sora had crests and beards. The breeder has no beardless silkies and from pictures and videos of her breeding pens is very picky about what she is breeding. I just look at my other three who are literal balls of fluff and then look at Sora. I mean Sora is still pretty in his own way and has the advantage of sight which the other 3 don't have. Been trying to put ponytails in their feathers to make it easier for them but Sora likes to pull them out and run off with them. Still would be nice if his crest could get a little fuller. He's got one hell of a beard though so at least I have that.
A lot of Silkie boys have a windswept backflowing crest as the streamers come in so maybe it's a guy thing with some of the boys. I have a Black Silkie hen that is not as thickly fluffed as the Partridge hen as far as body/tail fluff yet both have a nice crest (when they aren't matted). Our Partridge cockerel didn't have a full fluff head but had the windswept backward streamers. Our girls were more rounded fluff.
