I have been looking for a vertical feeder and waterer and have struggled to find any that come with everything I need (no drills necessary!) As well as are functional and affordable. I purchased this feeder (and also the matching waterer seen in my pics) which were both installed so easily, and came with all necessary parts, and exterior mounting kit to hang from the outside of the coop. When I filled the feeder, I did have to stick my hand in the little white hole where they eat out of, and pull some of the feed inside to allow more to fall down, but I did this to increase the visible mound of food so they would see more easily to learn how to use it. I'm confident once they learn how to eat from it, this step may not be necessary every time. Although honestly, it is an easy step for such a convenient system. This also looks like it will be way better at preventing pests than my previous gravity feeder.
The waterer is also exactly what I have been looking for and have struggled to find. I have been looking for a vertical waterer with nipple system, to hang inside the coop to spare floor space and mess. This RentACoop waterer came with every last thing I needed to be able to hang it in my coop, and also came with two watering cups as well as two nipples, and they even included one spare of each, and a kit to mount from the outside of the coop, if you want to. This went up so easily, and was filled so easily, and the chickens learned how to use it very quickly. Some figured it out on their own by their curious pecks, but others I picked up, and tapped their beaks against the nipple so they could feel the water come out. Once one figured it out, the rest followed.
Love this set so much, YOU NEED THESE!!
