Sex of 8 week old polish chicks

[Dfr06]

I hatched out 5 polish chicks in June. 3 normals, 1 frizzle, and 1 I think is a frazzled. I know for certain 1 is a male since he started to crow. I thought I knew the sexes but I'm now wondering if I got them all wrong( I thought the one that crowed was female the entire time). So here they are

1st and 3rd are the normals, 2nd is a frizzle, and 4th is the suspected frazzle

1 and 3 are almost certainly cockerels, they have sizable wattles for their age and I think I see some pointy crest feathers coming in.
2 and 4 look like pullets, but it can be a little harder to tell with frizzles
Beautiful birds!

The first and third picture look like boys. The red wattles makes me think so

I agree!

Thanks. It seems I was completely off on all of them since I thought the frizzles were males and the normals were females just a week ago!
