If you are planing on putting them out at six weeks, I think so. I think 4 weeks is enough time to learn where to go. Especially if they like the coop and don’t free range (I’ve noticed when they do, it is harder for them to figure out where they are supposed to sleep) I would not put any perches in the run until you get back (if you were planing on it) then they’ll be more likely to roost in the coop. And I think getting an auto door is a good idea. That way you can rest easy knowing that they are safe at night. I love mine, I can leave days and not worry. It is also good just for every day, if it’s cold out or something and I don’t want to go out, I know the door will close and I don’t have to.
