I did a search on BYC first to see if there were threads on the subject of painting and staining but didn't quite find an answer to my question. I ordered a little pine coop and run and when it arrives I will be staining all of the exterior pieces with a deck stain or similar. The interior is untreated as well and it would be great to have the wood inside protected a bit from wear and tear. Is stained wood OK to have around chickens? I wondered the same thing about paint...won't they be curious and peck at things? I have time.... The coop can be stained and left to "cure" until the end of March or possibly April. I also need to do work on predator proofing the bottom edges of the coop and run and do various things prior to the chicks' arrival.
