Like all animals, chickens need fresh, clean water to survive.  While researching the internet to determine the water solution that was right for me, I came across a plethora of quality products.  Here is a list of the most popular chicken waterer (prices are approximate):

WATER NIPPLES
These seem to be the product-of-choice these days.  They attach into just about anything (buckets, plastic bottles, PVC, etc) and most people report that their chickens learn to drink from them almost immediately.  Easy solution to keep water clean and accessible.  Water source can be outside the coop to make for easier filling. There are several types on the market and the choice is really personal preference.

Feeder Cups

CANTEENS
Standard waterer that hangs on the side/top of the coop or sits on the ground.  Benefits to a canteen style waterer are price, durability and ease of use. The downside is that they do not hold much water so you often have to place several around the coop.

AUTOMATIC FOUNTAIN
These off-the-shelf automatic fountains usually work using a pressurized water line (e.g. garden hose).  A valve will turn off the water once it reaches a certain level.  They do provide a constant flow of fresh water but they are prone to spillage.
