I'm looking for something or things that's going to be able to help keep a large rain barrel and piping from freezing over. I live in Michigan, so the winters can get harsh, especially living so close to the lake. Im wanting to put up a rain collection barrel that will be filled by the rain that's coming off the coop roof (over 250 sq ft of roof). From there, I plan on running a small hose or tube into the shelter (no more than 2 or 3 feet tops), that then connects to a horizontal pipe with watering cups for the birds to drink out of.
I just want to make sure i have something to keep the water from freezing in the barrel as well as the lines. I'm not afraid to put a little money in it so we have a good solid watering system the chicks won't run through and get their water all dirty, but can still be easily filled.
