so i have a couple question. i have 11 chickens, lost one to dog attack, the coop is 4x8, 7 ft tall in front with a sloping roof to back, this is where our ventilation is. there is a large triple pane window on the 8ft east side and a 2x2 ft wooden window on the south side that is open during nice weather. pop door on the north side that is always open and human door on west side. the coop is about 2 ft of the ground and is uninsulated 1/2 plywood. it seem to be draft free. the run is completely fence in, but i let them out of the run during the day to free range, they have arleady torn up the grass in the run, then close the run at sundown. we have the food under the coop which has chicken wire around it. we plan to cover in tarps to stop the wind and plan to put heat tap around waterer to keep from freezing. and maybe tarps around the south side of run, thats where we get most wind. so should i shut the pop door during winter? should i let them free range out of there run? and i have heard that they will stop laying in winter due to shorter days, should i put a light in to lengthen day time? how do there feet do in the snow, come jan. we have snow on the ground until middle of march. im not worried about them getting to cold. it is already dropping below freezing at night and it seem ok inside.
