Breeding Farm Loop: Cakes, Incubators and When to Mutate

This is the process guide, not the full mutation spreadsheet. Get a clean farm loop first; then use mutations and passives as the reason you keep hatching.

Build the loop

• Place Breeding Farms with easy chest access for cakes.
• Keep a kitchen producing Cake so pens never idle.
• Park incubators next to the farms.
• Filter a cake chest so transporters restock pens automatically.

Breeding Farm

Structures

Cake

Egg Incubator

Structures

Place a Pal Egg inside to incubate it.

Large Incubator

Structures

Device for incubating Pal eggs. It automatically maintains a suitable temperature and can hatch multiple eggs at once.

Cake

Food

A dish eaten during celebrations. Put it in the chest at a Breeding Farm to make Pals lay a particularly healthy egg.

Parents → egg → hatch

Assign two parents, supply Cake and wait for an egg. Move eggs to incubators and collect hatches on a timer. Use the breeding calculator when you need a specific child species.

Breeding Calculator

Mutations matter after parents already have the passives and IVs you want to keep. Hatch normals to lock a line; then push volume when hunting anomalies.
