Tho intrigued by the automatic watering systems, and having the skills and even most the parts to build one, I decided to start small at first to test the process, amounts and costs for producing fodder. Learned that it is possible to only water once a day by covering the trays to hold the moisture.I like it....sounds simplified...from some of the "big" systems....i am not ready to jump into "BIG" just yet....
It works for me at this point of having only 10 chooks and using it as a supplement instead of their main food source. I may set up a larger auto watering system at some point, or at least a rack to water all trays in one application of water.
