OK here is the question: I'd like to make a water source that restricts them from jumping and dirtying up the waterer, but also want to add a float so its automatic. Chickens of all sizes are using it so simply drilling big holes in the bucket wouldn't work. I'd like to set up a big pan that has a bucket in the middle, with holes in the bucket at the bottom, but not sure how a gravity fill would work with a float valve. Is that doable?
