I am getting about 10 keets soon. I have a 8x10 building that I have converted into a coop. Attached to that is a large outside area , old 14 x 30 dog run, accessed by a trap door. Then I have about 5 acres of free range area. Inside the 8x10 I have made a 44''x20'' brooder with a light. I can maintain 90+ degrees under the light even on a cool 60 degree night. My question is this, the 8x10 building will range 70-85 degrees. The brooder has been designed so that I can take out one section, so they can have full access to the 8x10 building. I know I need to keep them cooped for about 6 weeks, but how soon can I take out that section of the brooder so they can roam the 8x10? I will continue to leave the light on and would guess if they got cool at night, they would go back to the lighted area.
