Apr 12, 2022 · The event randomly chooses one upgraded Barn that isn't full (each with a chance equal to 0.55% * number of animals inside, e.g., 1.65% for three animals), then one random animal in that building. If no building is selected or the animal can't give birth ( e.g., it's a baby or pregnancy is disabled for that animal), the event does nothing.
