The coop was cold enough that my son went out and bought used fiberglas insulation and put it in the walls, covered it with heavy plastic. It was near zero, and we had to throw the chickens out, cause they kept eating the insulation as he was working. They stayed in the crawl space underneath till he finished late last night. When he went up this morning, they were pecking through the plastic and pulling out the insulation. He got cardboard and began stampling that over the lower half of the walls, but they went right through it. Right now he's cutting up an old carpet, which he is going to add, nailing that over the plastic. I pray that they can't peck through the carpet. Is there anything we can do to keep these danged chickens from going after the insulation, and how much damage can it have done. I'm not sure how much they ate. Is there something I can feed them to move it through. We are in the middle of a snowstorm and have no way to get anything today, or probably even tomorrow. All suggestions are welcome. Thanks.
