CompAnimalProduct is a comp class that is offered as alternative to base game's Milkable and Shearable, to allow animals to produce things that aren't milk or wool. It is customizable to produce a random item, as well as to sometimes produce additional items.
        //CompAnimalProduct builds upon both CompMilkable and CompShearable, with many more configuration options
        public int gatheringIntervalDays = 1;
        public int resourceAmount = 1;
        public ThingDef resourceDef = null;
        //customResourceString allows you to set a different string on the info panel
        public string customResourceString = "";
        //CompProperties_AnimalProduct allows an animal to produce random items
        public bool isRandom = false;
        public List<string> randomItems = null;

        few additional items, chosen from a list
