I have been watching the multiple winter water, winter heating posts coming through. It has made me think about my set up this year. I ended up deciding to keep my 600 gallon stock tank open for the winter for the ducks to swim and drink in. My goal is to keep their coop dryer over the winter. I do have 10 chickens that share the space with the 34 ducks, so I will need to put a water source away from where the ducks can get it. I am contemplating putting a heater into my coop this year. My coop is located under my garage, so starting a fire is a BIG worry! What does everyone use here??? I have used nothing over the last 5 years but dread that miserable look they all get when it gets cold!
