We're just finishing up our coop for our 18 "babies", and we are wanting to use natural roosts too - we have a few 3-4 inch diameter trees that we've recently cut down... Do any of you know whether pine and/or cedar trees are ok to use? Particularly I'm worried if the sap will bother their feet? (The logs are sticky right now, may dry out a little over time, I don't know) Any advice or experience with these? Thanks!!
