I've just finished putting ceiling insulation in my coop (a small, renovated horse barn) and it has made a big difference in keeping radiant heat out of the coop. I took some temperatures and the coop is staying in the mid eighties, while the center of the insulation read at 105, and the asphalt shingled roof is up to 140...all on a day when the high here is in the high eighties. Here's my question... The insulation's kraft paper is facing out, but is it necessary to cover the insulation with anything to keep the chickens from pecking at it? (They would have a hard time getting up to it, but they have a high roost and might be able to reach.) Also, what would be the result of a chicken ingesting fiberglass insulation? Any thoughts or experiences are appreciated!
