Has anyone else had problems with the big tin waterers? I have a 5 gallon waterer and it constantly leaks. I have had it completely level and up on cement blocks and it still pours out. This morning I went out to the hen house and the shavings were soaked again, around a 2-3 foot radius. I just cleaned the coop again yesterday and put in fresh shavings and now I have to pull all the wet shavings out again. I don't know if this is a manufacturer problem or an operator problem.:| I believe it is sealed correctly, you just twist the cover back onto the base. Anyone else experience this?
