Goat Mineral/Protein/Salt Block - Good for Geese?

[Omniskies]

Our feed store has a broken brown mineral block for goats that they are selling for a couple of dollars. I know geese love to gnaw on things and we always kept mineral blocks in with our rabbits. Does anyone know whether it'd be safe to give this to them?

The warning label says to not use it for sheep, but doesn't mention whether it's safe for horses, cows, deer, geese, etc.

* Don't think that much salt would be good for geese, honestly-- but, I don't have any of my own. Someone with geese will be along. . .
