Hi all! I live in VT and am already planning for winter in the coop. This is my first flock... My coop is 4x4 and about 6'4" sloping to 5' 6" tall. It has nice big windows on north and south sides, a human door and a chicken door that goes out to the run. I have 4 birds. The floor is already insulated and I plan to use the Deep Litter Method. I will put plastic over the windows once the cold weather starts and plan to insulate the ceiling to cut down on condensation. I will also weather strip around the door. What do others in cold climates do for warmth? Is insulating the walls necessary? I hope to only use the heat lamp on the super cold nights. Any input is appreciated!
