I put my four young ones out when they were about six or seven weeks old, but I'm a bit nuts in the chicken department. The first night, they all piled up against the door and fell asleep after crying for an hour. I saw them from the big girl side (2-door divided house) and felt completely awful. You might want to wait for more-sane people to answer that question.My five chicks are spending days outside and loving it. And I bring them back inside at night. They are four weeks old today. At what age do they stay in the coop all night? In their little run I have a low perch, food and water. I notice they try to dust bath in the dirt, so should I put a dust bath area in there? I have an old cat litter pan from ages ago that I just never got rid of, sitting in the garage collecting dust and odds and ends. Would this make a good dust bath, or is this unnecessary?

If you really wanted you, you could give them a dust bath area. Though, I find that they make their own areas in gardens! I have a designated dirt bath area in my pen and all of my chickens are very fond of it.
