I was also wondering if anyone could fill me in what you do for coop insulating? We bought the insulation, and were looking at having to buy plywood to cover it because I was under the impression that anything else they would just peck apart...but someone on here mentioned foam board. Does that work? I had assumed they'd peck that too, but if not that would be wonderful news as that plywood is not cheap, we're pretty broke after buying the automatic coop door and a rather elaborate 5th birthday party I'm throwing for my son this weekend haha.
