Has anyone used this on their coop for those small areas that aren't easily covered? If so, do you think this would work for the little openings between my corrugated metal roof and the 2 X 4 it is attached to? I have a small gap between roof and the wood it is screwed into. I was going to put a small piece of welded wire in the hole and spray foam over it. Will raccoons generally ignore it if they can't see through that area into the coop? Thanks for any help!
