This is the type of bowl I'm referring to.

Chickens tend not to walk in water when temps are below freezing.
The heated bowls of any kind aren't good for many breeds of roosters since to drink, they must dip their wattles in the water. Wet wattles will freeze and be frostbitten.
If it is elevated on bricks and large enough, you won't have to change it that often, and elevated so the rim is at back height, they won't walk in it.
A drinker cup system will freeze at night and when the chickens aren't drinking to bring in heated water. I'd estimate that about an hour at 20F and the water in the cup will freeze if it isn't constantly replenished with warm water. A little while later, the seal will freeze and before long any tubing leading to the cup will freeze with no heated water from the reservoir flowing into it.
Thermocubes will work for shutting off the heat when it gets above freezing.

I use an inline aquarium heater in a constantly circulating system.
