As for the mold, if you clean with regular vinegar and add a bit to your water it will help with that .
I find that the higher up the waterer is the cleaner it stays .
My coop is sand and they dust bathe in it , my waterer is up 12 inches off the ground with logs on 3 sides for them to stand on and drink ..
I hate those nipple waterers, I had them once and they stood forever to get a good drink , little sips are not a big gulp!! Also mine got green mold in them that I couldn’t see, my 5 gallon waterer with a tray is clear so I can see if it’s getting dark .
