I think it'd be nice to just set up an old school encounters chart for Hunt rolls. If you succeed you get your blood.
If you fail, you roll a couple dice and refer to a chart. Something like....
2-3 - Attacked by Hunters.
3-6 - Something less bad than Hunters
7-12 - Nothing happens.
8-whatever - etcetera
It's not a hard fix for scarcity but it does make the actual hunting a bit more entertaining rather than just 'you roll dice and get blood and if you fail you roll again. And you still get blood.'
