Crowing Rooster ..all night long

[BlindLemonChicken]

I would explore the predator option for sure. Even if your coop is secure a nearby rooster can trigger a cacophony in others. I heard the neighbors’ rooster alarming the other night probably half a mile away. That set off another rooster between them and us. Which set off my roosters. It was a 2 am ruckus that quieted down again until the usual time for pre-dawn crowing. It’s possible something distant is setting him off.

I seriously dont think we could plunge that coop intothat kind of darkness

Pitch black darkness shouldn't be necessary for birds to roost and be quiet. One of my coops sometimes gets very bright moonlight and there is no issue. I also have had house roosters for extended periods of time for various reasons and they always get a night light in their room so that they don't have a blind freak-out in a more confined space if something goes bump in the night. None of them have crowed all night just because it wasn't pitch black. If your lighting is really quite bright, like way more than you'd get with a good full moon on a clear night, then that could be disturbing the entire flock by preventing normal roosting behavior, and he might just be the only one actively complaining about it. However, if it's dim like moonlight or a night light in a bedroom, then I really doubt the light is the issue and would be looking for other disturbances, both inside and outside the coop. Just because he didn't sound off when he was younger doesn't mean there isn't some kind of routine disturbance setting him off now. While my roosters often sound off some time before I can see the dawn light (chicken vision being different to ours), if they get going at 2AM I know something is amiss out there, even if it's something they're technically safe from.

I have often heard crowing when the moon is really bright or headlights go down the road. Even mocking birds will be singing in the moonlight when it’s bright.

I would think the hens are not laying due to the short days rather than because of the crowing. My guess is that as the days grow longer you will start to see more eggs.
