Black Sexlink pullets?

[free range by day]

Back on November I purchased 15 black sexlink pullets from a hatchery. They are 12 weeks old. I keep hearing that black sexlink cockerels will be barred ( and I did end up with one by mistake, it is barred, you can see him in the background behind the waterer) . Why do so many of these pullets look like they have rooster feathers and red down their back? I though they only had ref on their chest. I’m just really nervous I have several black sexlink roos here?
Or do some of the pullets just have these curly feathers in the back like roos while they are growing? These are all 12 weeks old and photos of several of them. Thoughts ? Roos, hens?

All pullets. Any boys would be barred.

Looks like some of those birds are a GLW mix.

Pretty birds though. However GLW's can get a bit tempermental.
