I just wanted to mention that I've seen some folks that have used plain cheap steel as waterers.
Don't buy cheap pans that can rust or corrode.
Rust is one of the worst things your poultry can drink.
If you see any corrosion or rust forming, it would be wise to dispose of the container, waterer immediately.
Check your water containers, buckets, feed scoops and make sure there are no rust or harmfull chemicals that build up on or in them over time.
