Starting around 12 weeks is when gender specific saddle feathers are noticeable on non hen feathered breeds., usually more flowing close to 16 weeks
Barring width itself can be a lousy indicator of gender as it's quite subjective, especially when we're talking about hatchery/pet quality birds.
I also don't see any cockerels but disagree about the timing folks are stating that a male *will* crow.. I've seen it as early as 3 weeks and as late as almost 2 years old.. it truly depends on the individual in MY experience.
Gorgeous flock!
