The grocery store has bulk bins of seeds and dried fruits and that's where I get mine. Also, the health food store in town has organic ones, just a bit more expensive than Ingle's. I feed that to them once a week mostly, but sometime skip a week. Heck, buttermilk is very expensive these days, but no more so than chemicals and other less desirable stuff, right? In the winter, I use the buttermilk to cool down oatmeal a bit on a warm morning and add the seeds to that. They love it.
