I posted this somewhere else, and was told to try it here... I live in NWGA, where we don't get many nights that get below freezing, and when they do, usually not below 20 degrees. During the cold season I've been bringing in my four 1-gal waterers inside at night. I wash them and then fill them up with warm water in the mornings before taking them back outside. So far, not a problem. However, next week (Monday 1/6/14 & Tuesday 1/7/14), it's predicted to get to 7 degrees at night, with a high only in the mid-20's - That's 2 days without the temperatures getting above freezing. My current plan will not keep the water from freezing those 2 days. Running power to my pens is not an option. How can I keep the water from freezing without cords running to the coops?? Also, will my chickens survive 2 days with these temperatures, especially considering they are not used to it?? Would some hay be adequate enough to help keep them warm? Thanks in advance! This is my setup - I've got 3 separate pens, each with shelter, though the shelters are not insulated or even all the way closed. There are 13 chickens in the first pen, 6 chickens in the middle pen, and 12 chickens in the third pen. Each pen has a rooster.
