Is there any health concerns with using Particle board or wafer board in coop construction? I had a lady look at the coop I'm selling this weekend, and she was concerned about using particle and wafer board and the chickens scratching up the floor. She wondered if the glue in it was a health concern. I didn't know, I used plywood for the floor in this particular coop, but wafer board on the walls. Thought I'd ask before I build another.
