That de-icer looks good, but it has to go in water, right? I won't have open water in my coops, dangly wattles can get in that and freeze. I can't understand that the nipple things do and work like, beyond my comprehension.
I have had some severe problems now too with water freezing. Revamping ideas over and over and I think I found one that is working like a hot dam. It will take a bit of getting used to. I am used to filling my chicken waterers only every few days, I use big ones. Gotta get off my lazy butt and just pay more attention daily now to water, no problem. I can do that. the one gallon red base water font filled with warm water from my house, sitting in the warm water in the heated dog bowl. Fits perfectly inside the bowl, so no spills of water anywhere. Birds can only dip their beaks in, wattles won't fit. So, hoping this will work fine. I have also tried something else for my 5 gallon metal font. I popped into Canadian Tire the day before yesterday and purchased a single hot plate, it was on sale $15, regular $17, so not bad. I am trying it out for a couple of days to see how that works. Set on the setting below the lowest setting, almost to off, seems to be keeping the water in the moat in the metal font about 65 degrees. I am impressed, but only time will tell the tale if that will work or not. The metal font is wide enough that the chickens cannot peck at the dial and it faces against the wall. I'll report how that works, but so far, so good. Geeze, bring me summer, all this stuff to do with winter is a pain in my arse! Have an awesome day, CynthiaM.
