My chickens live in part of are barn. Before we got the chickens I would put a little bit of pinsol in to a gallon of water...in a watering can. And sprinkle it on the cement floor in the barn(makes the barn smell AWESOME!). I wouldn't sprinkle it in there section(the floor is covered with pine shavings). But could I still put pinsol in the barn to make it smell nice? Is it safe for them to breathe in?
