I wouldn't sprout millet or sorghum. Seem to recall that sprouted millet is guaranteed to develop mould toxins very quickly. Someone else could correct me on that, I'm sure. Sorghum isn't a great feed in any case and can contain enough cyanide to depress growth. I wouldn't sprout it and don't feed it.
Don't go near lupini beans (sometimes called lupines or even lupin beans), though 'sweet lupins' can be okay (not sprouted though). Often with the legumes it's best to cook rather than sprout, but there are exceptions. I feed sprouted dun peas, but not in high amounts (5% at most).
On the positive side, sprouted corn (if you can find the non GM varieties) are a terrific feed, and of course sprouted wheat is very good.
Best wishes,
