Egg Fertilizer

Egg Fertilizer mod preview for RimWorld

Fertilize unfertilized eggs without male animals — and do it immersively with your colonists.

Fertilize unfertilized eggs without male animals — and do it immersively with your colonists.

Colonists haul unfertilized eggs to the Egg Fertilizer Station, work the fertilization job, then carry fertilized eggs into an Egg Incubator for storage and faster hatching. Pairs perfectly with Eggs Across the Rim (buy eggs from traders, fertilize, incubate).

Requires Harmony (used for incubator hatch progress access).

WORKFLOW
1. Research Artificial Egg Fertilization (Electricity)
2. Build and power an Egg Fertilizer Station and an Egg Incubator
3. Ensure colonists have Crafting work enabled
4. Colonists pick up allowed unfertilized eggs on the map
5. They work at the station (configurable duration and success chance)
6. They deliver fertilized eggs into the incubator (Critical storage priority)
7. Incubator speeds hatch progress and protects eggs from deterioration

BUILDINGS
- Egg Fertilizer Station (2x1, Production) — interaction workbench for fertilization jobs
- Egg Incubator (3x3, Production) — stores fertilized eggs, accelerates hatching

EGG DETECTION
- Auto-scans vanilla and modded unfertilized/fertilized egg pairs at startup
- Station UI and settings: allow/deny specific egg types
- Rescan button when you add animal mods mid-game

MOOD
- Mood thoughts: fertilize success/fail stack on the worker; incubator hatch and power-loss thoughts are colony-wide and non-stacking

MOD SETTINGS (tabs)
- General — colonist jobs on/off, power, messages, scan stats
- Fertilize — work duration, high base success, Crafting skill bonus, mood toggles
- Prefer incubators for fertilized eggs (haulers prioritize incubators when built)
- Incubator — hatch speed, power, inspect detail
- Eggs — type filter list, compatibility scan toggles
- Debug — developer logging
- Presets: Reset to Normal Play / Reset to OP / Cheat

IMPORTANT
- Fertilization is pawn-driven (not magic map-wide auto-convert).
- "Colonists fertilize eggs (jobs)" must be ON for automatic work.
- Fertilized eggs should go into incubators, not sit on the floor.

Load after Harmony. Works great after Eggs Across the Rim.
