Morning ya'll! After buying my chicks in April, i have been thinking of ways to prevent their water from freezing. (I'm from Ohio) I've scoured this forum and found some really good ideas for coops without electric. But I was just thinking, cold-water fish have natural antifreeze in their bodies and scales to prevent them and the water around them from freezing. So couldn't I just add a crappie (or however many it'll take) into their tank of water to keep from freezing? crappies normally don't eat a lot in cold winter months, and i could just feed them wax worms every so often to keep the water from being too dirty. And since crappies don't eat much in the winter, they shouldn't produce too much waste.
I know this is a very odd method, but I think it'll work. Any ideas? Think this would work?
