Silent roosters...advice on when they are late crowers please

[NanaHess]

We have several potential Roo's but only 2 am I absolutely certain of. I am not zoned for roosters and have assured my neighbors that we will not have any. Of my 2 flocks not a single crow has even remotely been attempted.
The oldest flock is 19 weeks with the youngest flock at 8 weeks.
My question is are they all just shifty and hoping if they stay quite they won't wind up as dinner? Or are my 19 weeks still in the normal "not yet crowing" window? I see on the forums that some are crowing much younger but I have held off naming any potential edibles.
Here are my suspects.

Lavender Orpington @ 18 weeks ~ this is a given even though he is silent


Black Copper Maran when he/she was 16 weeks


These are all from the younger flock taken at 7 weeks, supposed to be Lavender Orpington, Blue Copper Maran and Ameraucana




Thank you!

This is my first time with chickens, so I'm not that educated about them. But I have two 16 week old roosters and they never shut up and have been crowing for a long while now.

I had a serama roo start crowing at 6 weeks (25 weeks now), and I have a silent 14 week old sultan cockerel, 16 week old polish cockerel and suspected 18 week old silkie cockerel. They haven't made a peep yet. I think it just varies from bird to bird.

My roosters all start at different times. I find that if they are among many other young boys it may take them even longer, whereas if they hear an adult rooster's example they will start earlier.

That makes sense since I seem to have a coop full of boys, I think I would have had better luck with just buying straight run chicks!
My first hen just starting laying last week so it goes along with the learning curve I suppose.
Hopefully she teaches the rest of the girls how to lay before the big purple guy figures out how to crow and teaches the rest of his kind!
Thanks

So yes, all of those are Roos.
But, you may be able to keep one. There's a 'rooster box' , it's a well ventilated box that's meant to stay darker then the actual world is. So, while a typical rooster on a farm may start crowing at 4 am, the rooster box keeps it dark, so the roo thinks its night, and will sleep. You'll need to ventilate it while still keeping it darker. Food and water should be offered, but other then that, it should be fairly small. So basically, you can have it crow at 12 in the afternoon where it's less obnoxious. But you'll need to talk to the town laws and have your neighbors sign a petition thing.

But roosters tend to crow when their ready, but once hearing a crow they're more likely to try crowing
