Pick a preset like Oxen, Horses or Llamas, or describe your own: what males, females and young are called, gestation or incubation days, weaning age, what you collect (milk, eggs, wool) and how much room each animal needs. Your new type gets the same tools as every other tracker: records, breeding due dates, health with withdrawal holds, weights, processing, a space guide, and expenses that flow into your Farm Ledger.
