I have always had the port gravity feeders, little to no waste and when their empty I pour the dust into a rubber bowl and make a mash. I recently added a hanging feeder but that will be for all the grow outs (lots of chicks this year) I probably won't use it after they're gone. As far as watering, I started with the cups but they get super gross really fast so I switched to nipples. I have a 5 gallon bucket in the run with nipples on it, and another 5 gallon bucket outside the run on a little table, it has a 6ft garden hose attached that connects to a 2ft long peice of pvc pipe with nipples that is screwed to the outside wall of my coop.
