It's not the chickens bumping it (they do), it's a slow steady drip drip around the seal between the white tank and the red base (it's the 3 1/2 gallon waterer. It got especially bad when I tried to put a floating watering puck in there, but it leaks w/o it. Leaks when hanging so I put it on blocks -- it still leaks. I'm really irritated because my coop isn't going to last long wet.
