Hi there! We'll be moving in the fall and I was scoping out areas for my coop and run. The property has an old, excellent condition shed on the property that would convert to a great coop, it has power already and it's in a good location. However there is a group of cedar trees directly behind it that would be incorporated in to the run area. I remembered seeing something about cedar being toxic to chickens. Is it just shavings because of the smell and oils? Would having cedar trees in the run area be harmful to my chickens? Thanks for your advice!
