Passive inheritance odds and how to speed up cake cycles
Passive breeding is a numbers game — the faster your cake loop runs, the more rolls you get per hour. A tuned ranch turns a multi-hour grind into a handful of cycles.

The odds in practice
With a two-passive donor pair sharing the same two passives, roughly 70% of eggs carry at least one target passive and about 30% carry both. Expect 8–15 eggs to land a clean four-passive result.
Cake throughput
One Cake needs 5 Flour, 8 Red Berries, 7 Milk, 8 Eggs and 2 Honey. Two Mozzarinas, two Chikipis and two Beegardes on a Ranch, plus a Wheat Plantation and a Mill, keeps a Breeding Farm running without manual restocking.
Hatch faster
Match the Egg Incubator temperature to the egg type with Heater or Cooler upgrades, and enable the server setting for faster hatch time on private worlds to cut each roll to minutes.
Track the line
Name each donor after its passives so you never breed away a stack by accident, and keep one spare copy of every four-passive donor in the Palbox.
