So, I know you're not supossed to use cedar shavings for bedding in a chicken coop. I've been converting an old (10 years+) workshop into my coop. My boyfriend just mentioned today that he thinks part of the shelving in the new coop may be cedar, based on smell. Will this still be a problem? It's not nearly as strong as fresh shavings would be, but there is a faint woodsy aroma. What does it look like if chickens are having a reaction to cedar? Chicks are currently still in the brooder. Do I need to start from scratch with a new coop?
