Chicks crowing at 10 /11 weeks... definitely roosters?

[RockNRollGardens]

We got 6 older chickens and 3 started crowing, one is a small white frizzle mix(I think it's a silkie not frizzle because they have 5 toes), they have a semi big wattle and comb. We have a Golden Laced Wyonnadette (I think I spelled that wrong) who is huge but has no wattle and a small comb, we thought she stood like a hen but we are new to this, they are very aggressive. Then there is the black easter egger that has big tail feathers barely any comb or wattle. I am attaching what pics I have but will attach more soon.
The age of the chicks are unknown, on the 26th of April I was told they were 6 to 7 weeks but I suspect one or two may be older. So I'm thinking 11 weeks maybe older I don't know.

Individual pictures would help for gender ID - I see at least 3 cockerels in your flock.

I could most definitely be wrong. I’ve been around chickens my entire life, but I’m only 4 months into being a flock owner and I’m learning a lot.
