I've thought about hanging one of those oil filled jobs in my coop. I can hang it from the ceiling to where the birds can't get on it to roost. I do use one in my back room but keep it on medium. Just enough to raise the temp. 30* in the BR hoop coop this afternoon and I found an EGG! First in a long long time. Bet if I get a light in there things will pick up. Yes VMdanielsen I do pay for horse manure. This however was already bagged. I have shoveled it myself for free though. When I did buy it I did have to drive a ways to get it. You can not beat horse manure IMO. Something the horse does inside that turns it into gold. I went to a plant sale where they were selling it in bags for $5. If I was you I'd bag it and sell it. I know I'd pay for it. Like I said even a couple dollars a bag is better than nothing.
