Could you simply hang your current bucket system? Sounds like it was working fine until they were getting knocked over.My chickens are drinking upwards of 5 gallons a day and by the time I get around to refilling them their waters wind up going dry more often than I would like. I tried a diy vacuum waterer (basically 5gal buckets sitting in pans) and that worked great until my chickens figured out how to knock over 5gal buckets full of water (I have no idea how they could possibly do it, but here we are).
So, I need a solution that will allow me to have at least a 20 gallon or so water capacity. Are those nipple waterers actually worth it? They seem like the sort of gimmicky thing that sounds good but never works for me.
