I purchased a heated waterer last fall. I have it sitting on bricks to keep the wood chips out of it. I stripped out the coop yesterday for a spring cleaning. A small section of coop floor was soaked and black from the waterer leaking. It is a 3 gallon with a stopper in the bottom for filling. The stopper drips all the time. I took it out and replaced it with a 1 gallon type with a screw off bottom. The old stand by. Has anyone else had this problem? I can't think of a way of fixing it. I also notice the water level comes right up to the top of the bowl. Any movement from the chickens and the water spills. I hate to spend $35.00 for the waterer and can't use it.
