Winterizing Chicken Coop

[BuckinghamFarm]

What are dimensions of shed...in feet by feet?
How many birds do you have?
What is your climate? putting your location in your profile can really helps folks give better answers/suggestions.

I'd put the pop door going into the run towards the front of shed, 8" above ground level.
Poop board with roost above in back of shed, opposite shed people doors....nests underneath and maybe feeder hanging there too.
Where are you going to bring the power in?
You're going to need to put some ventilation in shed too....probably gable vents would work best.
Is there another window on other side of shed?

The shed is about 5X5 and probably 8 ft in height. I have 6 RIR and would eventually like to get more. I just updated my profile to include my location (Thanks!) I am in Southern CT. The winters here get pretty cold for about 3 months. I can bring power into the shed from anywhere up high where the gals wont be able to get to it. I can cut some vents in the gables no problem thanks for that suggestion. Unfortunately there is just that one window on the run side.
