The amount of sheep summoned is the amount of targets this spell can affect.The sheep only act in unison and  count as familiars. Upon dying, the sheep poof into small harmless pink clouds. The flock of sheep have a combined health total of 2× times your 1d6 roll. The sheep stay summoned until either a minute or if the caster's concentration is lost. The targets must make a DEX saving throw (DC14) or suffer either the healing or damage effect. However, he targets can willingly fail the dexterity save.
