I have hung mine with a piece of chain. I put a snap at the bottom of the chain so that I can easily take it down to fill. My run is covered with a steel roof, so I screwed a j-hook into a ceiling joist to hang the chain from. One of the benefits is that I have been able to raise the feeder...
I also want to add that I was worried that my chicks would have trouble figuring this feeder out. That was an ill placed fear. They figured it out on no time.
Now, with this feeder and a nipple watering system fed from a rain barrel filled from runoff from my run roof, I could leave my flock...
I also used a jig saw since I couldn't see spending $25 for a drill bit for two holes. I started a tad small and used a razor knife to trim the edges to make a tight fit. Be careful with that razor blade, though!!!
