I have several of these poultry drinkers. I have the 6.5 gallon ones but am looking for the 3.5 gallon ones. The ones I have seen cost as much as the 6.5 gallon drinkers. Most times I can fill them where I put them but some not. I do have auto waters at my coops but these are nice to have but would like a couple of the smaller 3.5 gallon drinkers. I have had some that have leaked but it is usually my fault. I have others that are worse and if you don't have the other drinkers absolutely level, they will leak all of the water out.
