Our chicks are still in the garage in a brooder with a heat lamp because of freezing temps at night. All but the silkie sleep on the little roosting bar I have in their brooder. The others are 2 Barred Rocks, 1 Brown Leghorn, 2 Easter Eggers, 1 Black Sex Link, and 1 Lavender Orpington. They are 4.5-6.5 weeks old. I plan to move them to the coop in the next 2-3 weeks depending on weather. Our roosting bars are 3.5-4.5 feet off the ground. We have a ladder leading to the bars. Will they roost up there at 6-8 weeks of age? The coop is designed with hardware cloth along the bottom half and plywood along the top half to act as a wind barrier when they are roosting or laying on the other side of the coop. Is it too high? When I let them play in the coop/run on warmer days they do not climb the ladder. Their current little bar in the brooder is only about 4-6 inches off the ground. Thanks! (We can put plywood around the bottom half too on the roosting side of there coop and add lower bars if this is better, but then the bars would be lower than the nesting boxes. Below is picture of the coop. It is now enclosed in a larger chain link fenced area that is 6 ft high where they will play during the day. The ladder to the bars is not in this picture.
