Like you we are raising our first flock. We moved the 7 chicks out to the coop at 5 weeks. Southeastern Mass. It was still a bit cold, but they didn't seem to mind. Because the run was not done. They spent their first 6 days in the coop 4x8. I moved one of the two movable roosts down resting on cinder blocks. After two days they were roosting on the one higher up, so I moved the other one to the regular height. When I finally got the run done, I just opened the door and they went out. They have been going in at dusk each night. No chasing. In the left corner of the picture of coop and run, you can see an ornamental solar chicken light. At night, I place this in the run up by a window. It gives the chicks a bit of light. There is currently no electricity in the coop.
