Hi, I was given a coop my neighbor started to make for chickens he planned to have, but he decided not to complete the project. I have been working from this coop, expanding it, added another nesting box, etc. However, I have begun to believe he might have used cedar fencing boards. Now I am reading that cedar is toxic to chickens (reading about bedding). Does this extend to a coop partially built of cedar? Should I tear down and start over from scratch? Or will the weathering of the wood (it's been sitting outside for a year or so) remove the toxicity (if that is even possible). I'm sorry, if these have no brainer answers!
