the rust won't hurt the chickens..
Vinegar is acidic , so that is why it is hard on metal.
do like Cooties mentioned. use plastic waterers with the vinegar.
In the summer, the vinegar retards mold in your waterer.
at least it seems like mold, the black slime that builds up in the waterers. maybe all water does not do this, but my well water does.
eta: if your metal waterer is rusty, eventually it will get a pin hole in it. If that happens, all of your water will leak out .
you can patch the pin holes with
I am going to experiment with Gorilla Glue on my next pin hole.
Easier to use and a little goes a long way.
I know it holds water, because I accidentally plugged up my kitchen sink with it.. that's what gave me the idea to use it for pin holes..
