When we first started the poultry farm the biggest part of the chores each day was cleaning and filling all the waterers. It seemed the waterers were always full of gunk and muck, it was just to much to deal with. The bigger the farm grew the bigger the water burden. Not to mention in the winter the water was always froze and that was a huge problem. We put our minds together and started thinking. Low and behold if it wasn't my brilliant mind that came up with the solution. I said honey running water won't freeze correct, he thought that was correct. So we came up with an idea. We actually supply water three different ways depending on what time of the year it is.
During the spring months when we're getting frequent rain showers we have a very small creek that runs down the middle of our farm right between the two barns.
During the summer months we also run the water through the grow out pens for the young pullets. This is disconnected during the winter months and no birds are kept out here
During the winter months we need to do things a bit different. The first year we used this system we found that running water will freeze. When the water freezes up and you have 300 or so chickens without water you've got trouble!! Once again we switch to another method. We use a large stock tank filled with water and a stock tank heater to keep the water warm enough to make it all the way through both barns and back into the tank without freezing. This is where we start using the Goldfish pond pumps again. The water tank is emptied each night and refilled with fresh water.
It's amazing how the chickens will notice instantly if we turn the water off and it's like they are dying of thirst. We turn it back on 5 minutes later and they drink like crazy, they are so funny.
Hope this was helpful, it works well for us.
