I can’t visualize what you are describing here. Do you have a photo or a link?
I bought one of these a few years ago. Works great:

I’ve also made a DIY one from an empty kitty litter pail and a fish aquarium heater. That one is almost 6 years old and still going strong. It doesn’t hang. I set it on top of cement blocks to get the nipples at chicken face level. You can find the horizontal chicken nipples easily on line.
I also have several of the blue heated dog dishes from TSC. I do concur, get the TSC warranty. I’ve had some last for over 5 years and some konk out in less than one season. One thing I’ve found to cut down on wattles getting dipped and birds perching on the sides is to put one of these inside the blue bowl:

It also adds a little bit to the capacity.
