So I've recently finished building my first coop and run and am debating if I should poly the run since parts of it have direct ground contact. I did poly the coop, but have not put poly on the run. I used pressure treated for ground contact 2x4s which is why I'm not sure if I'm supposed to/need to poly them. I live in GA and it rains a lot (also termites) and I want this coop and run to last.
