Polish boys or girls

Ok I'm having a hard time trying to sex my silver laced polish as they don't seem to grow waddles (but a few pics do). I have been googling pictures but they mostly seem to be of full grown birds. From the pics it seems roos have white edges on their crest feathers and hend have white centers. Is this correct or are they 2 different varieties of the silver laced polish? If the coloring of the feathers is a correct assessment I'm in big trouble. They also don't seem to have pointy tail feathers (mine all have odd looking tails the top center feathers are short and the sides are longer) they look to stay broad and just get curved saddle feathers. Anyone more familiar with this breed than I?

I also have 4 white crested black polish they are all at a bit different stage waddles wise I am pretty sure 2 are boys, their doos are a bit uh unkempt looking lol

That is what I was thinking. I think the other 2 WCP are boys

Bit of an update. I am still not positive on my SL Polish here are some updates pictures. The last one is from a lady who got hers from the same batch as mine and it's way obvious that it's a ccockerel and he's been crowing for a while.That should mean I have all girls...right?

They are now 15 weeks old.
I should add they are a hatchery take on the breed so most likely not 100% pure from what I'm learning.
