Aggressive Hens?!

[slmwatts]

I hatched a batch of 28 back in March they are 19wk5days old. About 1.5 months ago I culled out 10 roosters. The ones I wasn’t sure about I kept in a separate pen. Sure enough another 7 are roosters. They are all in a pen together , next door to the coop. A couple of them don’t crow but look like roosters; one doesn’t crow and doesn’t have a tail but has shoulder feathers. Also, at least 3 of my “hens” posture at the pen and fight through the fence with the penned roosters, even though hens free range. My questions are 1) is it normal for roosters to not crow if kept in a group? 2) is it possible these aggressive “hens” are roosters that haven’t matured at 19 weeks?! (ETA: the hens aren’t laying yet)

Dominant roosters/cockerels can actually cause hormone depression in subordinates which may keep them from crowing. Possibly the aggressive 'hens' are cockerels. Pictures will tell the tale.
