Mine roosted on what would be the ceiling joists at 8' above the ground.. They had roosts at staggered heights that they used similar to stairs to get up to their roosts. They would fly down directly to the ground or if the main door was open, straight out into the run.

I start my keets at 90°F measured at the bedding level. They are ready to go to 80°F by the end of their two weeks in the brooder. I move them to the grow out pen at that time. Their only source of heat in the grow out pen is one red heat lamp that is 32" above the ground.
