Bucket Chicken Waterer A very widely used method of watering chickens is to find a bucket that has a tight-sealing lid, such as a 5-gallon paint bucket that has been thoroughly cleaned out. Get a flower pot drain pan or some other deep pan that is larger than your bucket by at least 5 or 6 inches and that is about 3 to 5 inches deep. Drill four to six 1/8- to 1/4-inch holes in the rim of the bucket with the lid on, about 2 inches from the top of the rim or just below the lid. Fill the bucket with water and put the lid on securely. Turn the bucket over into the pan to allow the water to start dripping out into the pan. The water level will only rise as high as the holes are so as the chickens drink, the water will drip from the bucket slowly.

Why can't you have the holes at the bottom of the bucket and the lid at the top that you could just remove the lid and fill the bucket. I am wanting to add a bird bath dripper to the bucket to keep fresh water in it at all times. Would I need to seal around the pipe to create a vacuum?
