I just ordered one from my local feed store, the price was $31 plus shipping to get it to me tomorrow. He said he would guarantee it won't be more than 40 total. That is over 10 cheaper than I could get it online anywhere and it is next day shipping. But now I am worried about how well they work. We were exchanging out regular plastic waterers twice a day after they froze, but now one broke from the frozen water (we can't get out there more than that.) We are having low temps in the -20 range and they are talking about temps as low as -30 in the next couple days. Will the electric heated dish keep up inside the coop. We can hardly ever see our breath when inside the coop even though it isn't heated. We have 9 chickens inside a 4x8 coop and they refuse to come out when we open the door. Anyone have any experience with these?????? Good or bad??
