It's not just the comb I'm looking at. Its crest and tail feathers are rather point and longI'm so hoping you're wrong but I may just be in denial. Here's a collage. This comb really widened. No real waddles to speak of though. Our other white silkie has a wacky single comb.

But they're only 8 weeks which is really too young for positive guesses. Silkies are generally really hard to sex correctly till 5 or 6 months.
But it's still an itty bitty thing, so nothing's for certain for quite a while.
love the pick of the three "girls".
