It's almost winter. I was reminded this morning of this fact when I went out to the coop to take care of the girls and their water had frozen over night for the first time. For now I know if I bring the water in at night and give them fresh in the morning they will be fine through the day, but the warmer days won't last long. I figured now is a good time to spark the discussion of fresh water in winter and how to keep it thawed. What method or product do you use? (provide a web link to product page if possible) Pros: What do you like about it? Why does it work for you? Cons: What don't you like? Features that are lacking that you wish you had? How many seasons has this heater lasted? Do you have an alternative technique that does not require a power source? Do you use an economical alternative power source? i.e. small solar panel What is the size of your flock? (I'm throwing this in because what works for someone with 6 chickens might not be practical for someone with 60 chickens and vice versa) Do you put the water in the coop or the run? Average day/night temps/geographical location/any other pertinent weather info?? Thank you all in advance for your insight!
