Has anyone tried making use of the rain water to assist in getting water to the chickens? I've picked up a plastic 55 gallon drum, was thinking of putting gutters on my coop, and direct all rain water into the drum... and picking up a hand pump from Harber Freight... so I can on my morning runs to the coop.. just give it a couple of pumps and top of the waterer when needed? Just an idea... not quite automatic... but it beats walking down our hill, seeing if they need water.. then walking back up the hill and back again, if they do! If any have anything like this.. please post pics! Love ideas!
