"Sacrificial rod" to prevent Rust in Chicken Waterers?

[5148]

I am looking for a way to slow down rust in my galvanized waterer. I have an inkling that the presence of a penny or some other type of metal object in the waterer would prevent/slow down the corrosion process as a "sacrificial rod" does in a water heater (in human houses!). Any chemists or others with such knowledge? I do not want one more source of plastics in my diet. Thanks!!

Just but a replacement sacrificial anode that is made for hot water heaters.

Todays "copper" Pennies are only about 0.0625 gm of copper and are made out of zinc planchets (blanks).

Hot water tanks have a sacrificial rod that is made up of magnesium or aluminum that's formed around a steel core wire and is screwed into the top of the tank.
The "chemicals" that is in water has to "eat" through the protective magnesium or aluminum coating to get to the steel core wire.
When the protective coating is eaten away then you start to get rust in your water.
With that being said simply hanging a steel core wire in your waterer will not help.
