Ok so I know I have asked this once before. But my coop is well on its way now and time to find out for sure what I should do. I live in central Maine, 8x12 coop, 12 8 week old isa browns. Should I insulate the coop or put plastic between the inside and outside walls. I really want them to be comfortable this winter. They will have ventilation where the roof meets the walls and windows that won't be in in the summer and a screened door for summer and a door in the winter. I just don't know what to do for keeping them warm.....
My coop is the same size as yours. I would insulate better to do it now than regret not doing it. It keeps it Warmer in the winter & cooler in the summer. Just my 2 cents.
