I have a 10' by 20' coop for 19 chickens. I winterized the run with 2 sheets of 7 mil plastic. It feels so much warmer in there. I still need to cover the top part of the coop with plastic to keep the blowing snow, rain, and wind out. After that I am gonna try the DLM. But how many bags of shavings will I need to cover my coop and maybe run with 6 inches of the DLM? I need answers soon. I don't when we'll be getting snow. The weather is pointing towards a rough winter.
