Hi all! We are steadily working on our coop and starting to think about feed and watering systems. I see lots of options out there. We have a rain barrel that would like to utilize for watering. Anyone have a tried-and-true watering system using a rain barrel? Also wondering what the best feeding system is? Something that reduces waste and doesn't require me entering the run every time I need to feed them. Our run will have a hatch that can open from the side so I'm thinking some sort of PVC set up. We're starting from scratch, so open to any and all suggestions.Thanks!
