9-13 2 Birds
Aim first red bird at pig in front, try to destabilize main building.
Aim second red bird to clear up remaining debris/pigs in main building.
(I hit this level on the first few tries, so the building destabilization may have been a fluke. If so then perhaps aim second red bird at windows above to destabilize building and perhaps third bird to clean up)
