Are these the beginning of rooster feathers?
Well that's not good that would mean that 5 out of the six chicks are male talk about bad luckIt looks like you've a couple of boys!
I'm not seeing rooster saddle feathers in the pictures. Saddle feathers are something different than tail feathers. If they're only 15 weeks old, I'm not sure comb color would be an indicator yet since you have probably another month or two before laying.
