My 37/38" Eddy can just reach the 100 gal trough if it's full. When the water level drops down he cannot. Thus I use a plastic muck bucket that I keep outside for his water which is perfect--untill it freezes so hard I can't break the ice up with a hammer. So, with latest bit of icy dicey weather I've been bailing water out of the big, and heated, trough and putting it in buckets (on the ground) inside the stall but that water freezes up soon when it's cold enough. I'd like to find a container and heater that will work for Eddy. I know they have heated buckets but I would like to find something with more capacity. Any suggestions? I'm guessing there wouldn't be any heater that would be safe to leave in a plastic muck bucket?! Thanks!
