Poisoned animal feed

Poisoned animal feed is an item obtained from Councillor Halgrive in the beginning of the Sheep Herder quest. It is used to poison the Plague sheep in order to get Plagued sheep remains. Doing so produces the message:
 * "you give the sheep poisoned sheep feed
 * the sheep collapses to the floor and dies"

The poisoned animal feed is not kept on death even if the player has 3 or less items with them.
