I use local hay - I put an ad in the local craigslist looking for someone selling hay. I think I specified, had to be horse hay, had to be a grass hay mix (lots of people farm alfalfa by itself around here). Found someone who grows hay for their horses and sells it, mix of timothy, orchard grass, alfalfa, and rye. Very nice. Not the greenest hay you ever saw, but it smells awesome and the chins love it! When I first got my first bale from them, I was a bit leery because I was used to the bright green hay from the pet store... while parts of it (the orchard grass parts) are that green, the rest is less than vibrant -- but our chins eat it like it's candy! So while I'd prefer greener hay, apparently for some chins it's not a huge factor.
