Hi, I had a thought on how to heat the chickens water container, it's about a 20 gallon trough. We in Northern Mi. and have almost 100 chicken, I've always just used a drop in a heater for the winter months. The chickens are kept close to the house and on the same side of the house is our boiler which heats our home. There is maybe 10ft from where the water sits and the exhaust comes from our boiler. My thought is to use the exhaust, which is very warm to heat water. I would not directly heat the water only the trough which will heat the water. I would have to extend the exhaust pipe and build a wood structure to protect the water from contamination. Please any thoughts on this idea is appreciated.
