ChooksNquilts, this sounds like mine! I learned that it has nothing to do with them coming in from outside. We had 2 rainy days and I kept them inside. They were happy all day long. Then bedtime rolled around, and like clockwork they started freaking out. I can't stand hearing it so I always end up taking them out and holding them until they fall asleep. Last night I crawled in their cage and sat like a contorted idiot in the pine shavings holding them until they were out. The entire lower half of my body had fallen asleep. Then I spent the next 20 minutes ever so slowly loosening my grip and moving away and out of the cage. This is ridiculous! Am I encouraging this behavior by babying them!?
I will usually sit with mine in a lawn chair just outside the run.
They start out in the run on the roosts out there peeping and getting up and down.
Then they start going into the coop going in and out.
As it starts getting darker, they are all in the coop but they all want to be right next to the door for some reason!
So they’re crammed in one corner next to the door.
I talk to them while they’re doing this and tell them how silly they’re being.
Somehow one of my cockerels ended up with a limp the last few days and I know it’s because of these bedtime shenanigans.
My coop is a prefab and it actually has 3 doors which I’m grateful for now because I’ll open them and pick up some of them and move them so they’re not so squished.
But most of the time they just go right back to the pile

They do quiet down when it gets darker.
I think they instinctively know that noise will give them away to predators.
I don’t know if you know but chickens have very poor night vision.
I just walk back to the house. My older birds are usually in their coop not long after the young ones. They don’t make such a fuss. It’s just a chick thing.
I think you have to bite the bullet and leave them to their peeping.
I’d hate for them to become used to you holding them as they fall asleep and they get bigger and bigger.
They’re in a safe coop, they’ll be fine!
Like I said, they settle down when it really gets dark.
All they really need is to just grow up.
They all go through this stage and they won’t have any trauma from it.
I do agree it’s hard to listen to...that’s why I go back in the house after the coop is locked up

Good luck to you!
You can do this!!
