Thanks to everyone who responded. Since they had been doing well together during the day the last couple days, I went ahead and followed the advice of just letting them be together tonight. I do have an automatic door and I just set it for a tad later to give the chicks enough time to come in from the run after the big hens, which is exactly what they did!
I left the brooder cage doors open so they could go in and pile up where they have been every night but not be as separated and it went well. I have a camera out there and watched closely until everyone was settled. There was a bit of flying around frantically by 2 or 3 of them for about 5 minutes but then they all started settling and have been sleeping happily in their pile since!
See pics below. It’s a bit hard to see since it’s dark, but I think you can see it well enough to know it was a success!
They will be 8 weeks old on Monday, so I know it could still be a couple weeks before they like to roost at night (or so I have read).
Just glad they knew to leave the run and come into the coop on their own!
Both the coop and run are predator safe but the coop is very much so.
Also, the water and food are in the run and now I am not concerned that they will get to it each day as they need to. I did leave one water container in their brooder cage too, just in case. Poop or bedding cannot get in it.
I still have 3 more days and 2 nights to watch them before we leave too!
Also, I do have someone that can check on them once or twice while I am gone. So I am feeling so much better now! Thanks to everyone for sharing!!
