that's what I use. Indestructible, horse-safe, contains the mess. When the ground gets too beat up around them, just roll them to a new spot. Plus it's good karma for recycling!
Here's one website in case you don't know what I'm talking about. http://www.bigskytirefeeders.com/
I got mine from guy in Illinois near the quad cities, but there's probably someone in your area too.
Thanx for pointing me to this. They definitely look like a economic alternative to the classic metal racks. But will the horses step inside?! And are they sort of sharp at the inside (where edge touches the wheel rim)?!
Maybe somebody around the Twin Cities uses/sells them so I could have a look?
Any other suggestion for a new or used hay feeder is appreciated.
“Only” problem is, that currently small bales are fed. So I am now thinking, wondering if it makes sense though, to look into a (smaller) round bale feeder that could also be used for big bales one day.
