Are all my baby Welsummer chicks pullets?

[Chipmunk Chicks]

I know these girls are barely 3 weeks, but I wanted to ask if all these Welsummer chicks look like pullets based on their head triangles? (Since they are supposed to be more easily sexed at hatch.) I feel like three look very dark and clear, and three are a little fuzzier.

Of course, I didn't see what they all look like mixed together at the hatchery to gauge what's normal range of variation for their line, so not seeing a known male to compare...

I can take better eyeliner shots of the ones in question if that helps.
Thanks!

I'm not familiar with sexing with triangle but these looks like pullets to me based only on what I can see of their combs for 3 week old single-combed chicks. Post again at 6 weeks

Look at their breasts. If they're feathering in reddish they're females.
Males would be feathering in mostly black

That's an amazing tip! Thank you! I will double check tomorrow, but so far I have only noticed reddish. Now we're all snuggled in for a nice evening cuddle so I won't disturb anyone.

Of what I could see in the pics all I spotted was pullets.

I hope you're ready for a whole bunch of chatty Kathy's They are great birds, very smart and friendly (I just love my Piper) but they definitely have something to say about everything
