Yes I think you would want to insulate! And this also helps keep them cool in summer too
I would not leave the insulation bare tho...chickens pick at EVERYTHING! lol We had a small opening where one of our panel sheets had been cut for an outlet opening..I painted it the same color hoping they would not "see" it. Well THAT was the first thing they went to and start pecking away! We had to cover that right away. THEN they started pecking at the outlets! So now I have child safety plugs in that! Chickens are SO nosy lol Their next adventure has been trying to fly up to the light bulb and get at that!
