Hi, I am building my first coop and plan to use metal corrugated roofing. I am concerned about the small gaps left in the corrugated "bumps." I know they sell wiggly, adhesive, foam strips to put in there. Has anyone used them? Do the chickens peck them or do the strips deteriorate in time? If you have left the "bumps" unblocked, have you had any problem with that? Also, has anyone who has used corrugated roofing without insulating undeneath it had problems with condensation in the coop? Thanks in advance!
