I have a PVC pipe feeder and I attach it with bungee cords to a metal stake. That way, I can put i wherever i want.I really love using a PVC feeder to keep the chickens from throwing food everywhere. In my last coop, I had 3" diameter pipe with a couple elbows at the bottom creating a U. It worked very well at not letting the chickens waste feed, but wouldn't stand up by itself and had to be attached to the wall. This time, I built one using 4" diameter pipe with a Y at the bottom, so that it has a flat base.
