To feed the Porker you must collect items from the Feeding Grounds. The items you can feed the Porker are Addled Egg, Bread Crust, Flaccid Salad, Old Meat, Potato Peelings, and Rotten Tomatoes. These items apparently expire after a certain time limit.
I was wondering how long these items last before they disappear? Does the timer start when they are on the ground or after you pick them up?
