I'm actually curious how you got those fifteen AOO's. I mean, I know the answer is Combat Reflexes, but that just gives you more Attacks of Opportunity to make. You still can only make one against any person, and only one for each opportunity they offer you. Vir activating an ability that provoked an AOO would only grant Sheerak one attack, unless she has something that lets her make all of her AOO's against someone for triggering one AOO.
As for the Chicken Avalanche, I've seen those joke feats, and that'd be hilarious. Just keep pulling out the material components for any spell where the components are 'seeds', 'bugs', or 'worms' and you'll either pull out Chickens, or Chicken Feed. In one round, after 2.45x1045 free actions, you'll do more damage to the local economy then every adventurer who ever lived in the history of ever.
