Panicking a bit over travel plans… need expert advice

[Thrilled Chicken Mama]

Brand new chicken mama with 11 chicks - 8 weeks old- and I am wondering if I can leave them for 4 days to travel for Thanksgiving.
The reason I am panicking is because when we bought our new house a few months ago, I inherited 5 adult hens and I have no idea how to leave the chicks separated for that long without them being confined to a fairly small space the whole time.
They have been in the coop and run with them for about 3 weeks but separated in a brooder cage when in the coop and a large dog crate when in the covered run until the last few days. As of the last couple days they have been together with full access to each other, and it finally seems like the adult hens are starting to accept them as part of the flock. Definitely have pecking order stuff going on but no longer seek to be aggressive with them for no reason. But this is only during the day and I am heavily supervising.
I still have to put the chicks back into the brooder cage at night because they do not know to go in on their own to roost at night yet and I don’t have time to solidly get them in that routine before I leave.

So after that long intro, my real question is… will they be ok staying in their brooder cage for 4 days?
I can make sure they have plenty of food and water, but it’s the space I’m worried about. The dimensions of the brooder cage are about 3 feet x 9 feet and the top of it sits about 3 feet high.
It actually seems fairly spacious in there but I am also worried because it is inside the coop. So they will miss out on sunshine and fresh air. (I have an exhaust fan and enough ventilation but they are low and sitting under the shelf so I still worry about it).
Obviously in addition to plenty of food and water, I will leave brand new fresh and dry bedding.

Sorry for the long post but wondering if anyone has any advice… either words of comfort that they will be fine or words of caution of why I should figure something else out for them. Not that I have any idea what that would be right now, other than me staying home lol.
But I am willing to do that before I will put my chicks in harms way.

Thank you for reading this long post!! And for any help you can offer!!

PS… posted a picture that’s not a great one but hopefully lets you see a little of the brooder cage. The chicks are all mostly inside and a couple out since the doors are open and a also a couple of the adult hens checking out what’s been behind those closed doors the last 3 weeks

Id stay home. If I went I’d just worry about them and wouldn’t have a good trip anyway.
Or get someone to watch them.

I think your setup sounds great. I don’t that is too small for 4 days. My only concern is that the chicks might knock over their feeder or waterer. Is that a possibility with your setup? I do think it would be a good idea to have someone check on them once around day 2 or more if you can. But I really don’t think you have anything to worry about.

Your coop looks really nice by the way!!!

Leave them in the coop. Have someone pop by to check on them. Theyll be fine.
Do not cancel family plans for somechickens, they'll be fine.

Honestly I'd just rush them through the rest of integration. They're already together during the day, so lock up the brooder permanently, and put them into the adult coop at night. They should be able to rehome themselves to the adult coop within a couple of days, even if they don't roost.

It's never taken me longer than a week and a half to get chicks (4 week olds) to coop up with adults.
