Our girls are 6 weeks old & in their coop, we have a tractor for them. At night we put them up in the top part & close the little ladder to keep them in there. We also still have the brooder light on at night for them, and we put their food & water up in the enclosed part as well. What I'm wondering is, do they need the food & water at night? And when did you all stop using the brooder lamp? It's not too cold here at night - it bounces between 40's and 50's at night - 70's during the day.
