What are the options for keeping water from freezing in winter?? I am going nuts with this issue. I bought a metal waterer and a metal base warmer from Tractor supply only to find out that you're not to use it with an extension cord, which was my plan because I do not have electricity to the coop. So my questions are: Is the extension cord definitely out of consideration due to fire hazard ? Just writing that warning on the instructions has made me stop before using it. I certainly don't want to burn down my coop or my house. Hasn't any company made a dependable battery operated water heater for those of us w/o electricity? Why not? If there are battery powered cars, why not a water heater for a coop? I haven't come across any threads that mention this, so I am guessing it does not exist. Does anybody know of one? If someone invented one, they'd solve the problem for a lot of people. So how do I deal with keeping water from freezing in winter? I saw a solar powered dish for 39$ but I don't know if it works. It says it has limitations, but has anyone tried it? It has to be outside of course, and on a cloudy winter day, well.... Please, please could someone say what is the way to handle this water issue for a coop without electricity? I am hoping that someone out there has had figured this out and will share the way to do this. Thank you in advance to all who have advice.
