Quote: I am not going to submerge them. I will actually make hangers so they hang in the bucket at a safe level. Some others have done this and it's worked, but they definitely didn't submerge them! Lol! I can only imagine what my chickens woud be saying about me, loudly!
If I can't make it work, then I will just bring them in every night or use my heated waterers.
If it is a newer fish tank heater, it is most likely 100% submersible~ For example, every heater at petsmart is submersible

My heaters are all at the bottom of my tanks, hidden behind stuff.
I too only use submersible heaters in my tanks. I have a 125 gallon tank, and a 46 gallon. It's been years since I have used anything else, in a tank. DH and I have kept aquariums most of our lives.
