You're close to San Jose, right?
If you're open to orchard grass hay, I have a suggestion. Check out the orchard grass hay at Andy's Pet SHop at 51 Notre Dame Ave in San Jose. They get their orchard grass hay from San's Downtown Feeds in San Jose, which is one of the two hay dealers that I use for the rescue. Andy's Pet Shop sells it in flakes, which is roughly 5-7 pounds at $1/pound. About 80% of the time, the orchard grass is awesome. It's sold in open top bags so you can actually examine it closely to see if it's what you want. If it happens to not be good, then you can check out the Oxbow hays that they carry, which cost more. At times the orchard grass hay is so good that piggies stop eating their veggies and move over to the new hay that I put in.
But I know how your piggy loves timothy seed heads, so she may not like orchard grass.
